Question: Who uses the Wind Tunnel tool?

Aerodynamics

Aerodynamics is one of the branches of dynamics that deals with the study of air movement, especially when the air interacts with solid objects.


Question: Who uses the Wind Tunnel tool?

Aerodynamics

Aerodynamics is a branch of fluid dynamics and gas dynamics, with many theories sharing each other between them.


Question: Who uses the Wind Tunnel tool?

Aerodynamics

Aerodynamics is often used synonymously with gas dynamics, with the difference that gas dynamics apply to all gases.


Question: Who uses the Wind Tunnel tool?

Aerodynamics

The description of Aerodynamics (science of motion force) comes from Greek that is water = air and dynamic = force of motion.


Question: Who uses the Wind Tunnel tool?

Aerodynamics

So it can be concluded that aerodynamics is a science that studies the movement of an object in the air.


Question: Who uses the Wind Tunnel tool?

Aerodynamics

Air force science is an advanced science of the older science, namely water motion force science or hydrodynamics and air motion force science is closely related to several other sciences namely natural science (physics), exact science (mathematics), force science (mechanics), and weather science (meteorogia) which provide basic information about silent air, especially about the changes experienced by air if the height increases.


Question: Who uses the Wind Tunnel tool?

Aerodynamics

In 1810 Sir George Canley argued that air is forced to blow opposite to the direction of motion of the wing in such air or fluid.


Question: Who uses the Wind Tunnel tool?

Aerodynamics

Later in 1871 Pranoim Wenham planned an airfoil that curved like a shape from a bird's wing.


Question: Who uses the Wind Tunnel tool?

Aerodynamics

It was also in this year it was Wenham who first made a steam-powered wind tunnel.


Question: Who uses the Wind Tunnel tool?

Aerodynamics

This airfoil investigation was continued by the Wreight brothers by conducting experiments of approximately 150 pieces of water foil in addition to equipping steering tools to drive aircraft in flight. In Iaanc Newton's investigation has found air styles through objects that moves that is the lifting force (lift and obstacle/drag).


Question: Who uses the Wind Tunnel tool?

Aerodynamics

In 1902-1907 N. Wilhelm Kutti (germany), N. E. Janhowaki (russia), Frederiek W. Launohoster (England) discovered a theory of how the lifting force (lift) occurs in airfoils.


Question: Who uses the Wind Tunnel tool?

Aerodynamics

With the discoveries in the years above it is clear that aerodynamics is a new science, and not an abstract knowledge such as exact science and mechanics because until now investigations are still being carried out.


Question: Who uses the Wind Tunnel tool?

Aerodynamics

Aerodynamics is actually nothing other than one that studies or investigates the properties of air, the reactions and consequences arising from the movement of air to objects passed by air or the movement of objects in the air.


Question: Who uses the Wind Tunnel tool?

Aerodynamics

So aerodynamics also means knowledge or investigation about the movements of objects in the air where this sense is very closely related to you flight.


Question: Who uses the Wind Tunnel tool?

Aerodynamics

As for factors affecting Aerodynamics: Temperature (air temperature) Air pressure Air velocity Density/density of air To study the science of aerodynamics, there are several laws between Newton's Law, Newton's Law iSays that a silent object will remain stationary while objects that moves will still move in a straight line and a fixed speedexcept for a reason from the outside that is the force that forces it to change the state Newton IIsays that the change in the number of movements is directly proportional to the working force and according to the working line of the force aforementioned.


Question: Who uses the Wind Tunnel tool?

Aerodynamics

Furthermore Newton II's Law says that a moving object will get a slowdown.


Question: Who uses the Wind Tunnel tool?

Aerodynamics

Newton's Law IIIsays that action is as large and in opposite direction to reaction.


Question: Who uses the Wind Tunnel tool?

Aerodynamics

It means that the force implemented by two objects against each other is equally large and in opposite directions.


Question: Who uses the Wind Tunnel tool?

Aerodynamics

Review Understanding the movement of air (often called the “flow field”) around an object allows calculation of the forces and moments acting on the object.


Question: Who uses the Wind Tunnel tool?

Aerodynamics

Similar properties calculated for a flow field include velocity, pressure, density, and temperature as a function of space and time position.


Question: Who uses the Wind Tunnel tool?

Aerodynamics

Aerodynamics allows the definition and solution of equations for the immutability of mass, momentum, and energy in air.


Question: Who uses the Wind Tunnel tool?

Aerodynamics

The use of aerodynamics through mathematical analysis, empiric emptiness, wind aisle experiments, and computer simulations formed the scientific foundation for aircraft and a number of other technologies.


Question: Who uses the Wind Tunnel tool?

Aerodynamics

Aerodynamic issues can be grouped according to the flow environment.


Question: Who uses the Wind Tunnel tool?

Aerodynamics

External aerodynamics is the study of flow around solid objects of different shapes.


Question: Who uses the Wind Tunnel tool?

Aerodynamics

The evaluation of the lift force and inhibitory force on a silent winged aircraft or the shock wave formed in front of the muzzle of the rocket are examples of external aerodynamics.


Question: Who uses the Wind Tunnel tool?

Aerodynamics

Internal aerodynamics is the study of flow through part-elongated inside a solid object.


Question: Who uses the Wind Tunnel tool?

Aerodynamics

For example, internal aerodynamics includes the study of air flow through an enjin jet or through an air-watering pipe.

Aerodynamics

Aerodynamic issues can also be grouped according to their comparison to the sound rate, i.e. the flow rate below, around, or above the rate of sound.


Question: Who uses the Wind Tunnel tool?

Aerodynamics

An issue is called subsonic if all the rates in the matter are smaller than the sound rate, transonic if rates above and below the sound rate are both present (usually when the characteristic rate almost equals the sound rate), supersonic when the characteristic flow rate is greater than the rate of sound, and is hypersonic when the flow rate is very-more-large than the rate of sound.


Question: Who uses the Wind Tunnel tool?

Aerodynamics

The aerodynamicists are not unanimous in terms of the precision of the definition of hypersonic flow; the minimum Mach numbers for hypersonic flow are in the range of 3 to 12.


Question: Who uses the Wind Tunnel tool?

Aerodynamics

The influence of viscosity in the flow provides a third classification.


Question: Who uses the Wind Tunnel tool?

Aerodynamics

Some issues may encounter only a very small viscous effect on the solution, in which cases of viscosity are considered negligible.


Question: Who uses the Wind Tunnel tool?

Aerodynamics

Important to these issues is called invisid flow.


Question: Who uses the Wind Tunnel tool?

Aerodynamics

Flow in which viscosity cannot be ignored is called viscous flow.


Question: Who uses the Wind Tunnel tool?

Aerodynamics

History of early ideas — ancient times until the 17th century Humans have utilized aerodynamic styles for thousands of years in the form of sailing ships and windmills. [1]


Question: Who uses the Wind Tunnel tool?

Aerodynamics

Images and tales of flight have appeared throughout written history, [2] for example the legendary story of Icarus and Daedalus. [3]


Question: Who uses the Wind Tunnel tool?

Aerodynamics

Although observations of some aerodynamic effects such as wind resistance (for example shear forces) have been written by Aristotle, Leonardo da Vinci, and Galileo Galilei, very little effort has been made to develop an overarching quantitative theory regarding airflow before the 17th century.


Question: Who uses the Wind Tunnel tool?

Aerodynamics

In 1505, Leonardo da Vinci wrote Kodex on the Flight of Birds, one of his earliest treatises on aerodynamics.


Question: Who uses the Wind Tunnel tool?

Aerodynamics

He wrote for the first time that the center of mass of a bird in flight was not coincident with its center of pressure, and he explained the construction of an orniopter, with flapping wings, similar to the wings of a bird.


Question: Who uses the Wind Tunnel tool?

Aerodynamics

Sir Isaac Newton was the first to develop the theory of air inertness, [4] making him one of the premier aerodynamicists.


Question: Who uses the Wind Tunnel tool?

Aerodynamics

As part of that theory, Newton viewed that shifts were caused by the dimensions of objects, fluid density, and velocity of rank two.


Question: Who uses the Wind Tunnel tool?

Aerodynamics

This all proved true for low flow rates.


Question: Who uses the Wind Tunnel tool?

Aerodynamics

Newton also developed a law for shear forces on flat slabs that skew toward fluid flow.


Question: Who uses the Wind Tunnel tool?

Aerodynamics

Using F for shear force, ρ for density, S for flat slab area, V for flow velocity, and θ for skew angle, this law is presented as F = ρ S V 2 sin 2 (θ) {\ displaystyle F=\ rho SV^ {2}\ sin^ {2} {2} (\ theta)} This equation is incorrect for shift calculation in the vast majority of cases.


Question: Who uses the Wind Tunnel tool?

Aerodynamics

The shift on a flat slab is close to linear with the angle of inclination, inversely quadratic with action at a small angle.


Question: Who uses the Wind Tunnel tool?

Aerodynamics

Newton's formula can herd one into believing that flight is more difficult than it really is, because it misestimates this shift and thus also the necessary thrust force, and this circumstance partakes in delaying human flight.


Question: Who uses the Wind Tunnel tool?

Aerodynamics

However, this formula is more correctly used for very slender slabs when angles enlarge and flow separation occurs, or if the flow rate is classified as supersonic. [5]


Question: Who uses the Wind Tunnel tool?

Aerodynamics

Modern beginnings — 18th to 19th centuries In 1738 Dutch-Swiss mathematician Daniel Bernoulli published Hydrodynamica, in which he explained the fundamental relationship between pressure, density, and velocity; in particular Bernoulli's principle, a method for calculating lifting forces aerodynamics. [6]


Question: Who uses the Wind Tunnel tool?

Aerodynamics

The more general equations of fluid flow - the Euler equations - were published by Leonhard Euler in 1757.


Question: Who uses the Wind Tunnel tool?

Aerodynamics

The Euler equations were extended to incorporate the effects of viscosity on the first paro of the 1800s decade, yielding the equations—the Navier—Stokes equations.


Question: Who uses the Wind Tunnel tool?

Aerodynamics

Sir George Cayley is recognized as the first to recognize four aerodynamic forces in flight; namely weight force, lifting force, inhibition force, and thrust force—and the relationship between them. [7] [8] Cayley believed that the inhibitory force on a flying machine should be “resisted”, in the sense that by power locomotion to bring up the level of flight.


Question: Who uses the Wind Tunnel tool?

Aerodynamics

Cayley also noticed aerodynamic wake-up properties with a low inhibitory force.


Question: Who uses the Wind Tunnel tool?

Aerodynamics

Among the wakes he investigated were a cross-section of forel (trout).


Question: Who uses the Wind Tunnel tool?

Aerodynamics

This may arise against intuition; however, the bodies of fish are shaped to produce very low drag when they move and move around in the water.


Question: Who uses the Wind Tunnel tool?

Aerodynamics

Their cross-section is sometimes very close to that of modern airfoils styled low inhibitors.


Question: Who uses the Wind Tunnel tool?

Aerodynamics

Experiments investigating air resistance were conducted by researchers in the 18th and 19th centuries.


Question: Who uses the Wind Tunnel tool?

Aerodynamics

The theories of inhibitory style were developed by Jean le Rond d'Alembert, [9] Gustav Kirchhoff, [10] and Lord Rayleigh. [11]


Question: Who uses the Wind Tunnel tool?

Aerodynamics

The equations for fluid flow along with the friction force were developed by Claude-Louis Navier [12] and George Gabriel Stokes. [13]


Question: Who uses the Wind Tunnel tool?

Aerodynamics

To simulate fluid flow, there are many experiments involving objects drowning within the water current or simply by dropping those objects from the top of a tall building.


Question: Who uses the Wind Tunnel tool?

Aerodynamics

Towards the end of this period, Gustave Eiffel used his Eiffel Tower to assist him in the flat plate fall test.


Question: Who uses the Wind Tunnel tool?

Aerodynamics

A more careful way to measure the inhibitory force is to place an object inside a uniformly regulated artificial air current, where velocity is known.


Question: Who uses the Wind Tunnel tool?

Aerodynamics

The first person to conduct this experiment was Francis Herbert Wenham, who also built a wind tunnel experiment in 1871.


Question: Who uses the Wind Tunnel tool?

Aerodynamics

Wenham was also a member of the first professional organization devoted to aeronautical affairs, the Royal Aeronautical Society, in the United Kingdom.


Question: Who uses the Wind Tunnel tool?

Aerodynamics

Objects placed inside wind tunnel models are almost always smaller than those that occur in the actual state, so this method is necessary to connect small-scale models with their analogues in real life.


Question: Who uses the Wind Tunnel tool?

Aerodynamics

This was achieved through the discovery of dimensionless Reynolds numbers by Osborne Reynolds. [14]


Question: Who uses the Wind Tunnel tool?

Aerodynamics

Reynolds also conducted flow switching experiments, from laminar flow to turbulence flow in 1883.


Question: Who uses the Wind Tunnel tool?

Aerodynamics

At the end of the 19th century, two problems were known before the realization of the flight of objects heavier than air.


Question: Who uses the Wind Tunnel tool?

Aerodynamics

The first is the creation of an aerodynamic wing that is low in its inhibition style, but the height of the lifting force.


Question: Who uses the Wind Tunnel tool?

Aerodynamics

The second issue is how to determine the power required to maintain a hovering state.


Question: Who uses the Wind Tunnel tool?

Aerodynamics

In this time, the foundation of knowledge has been pioneered for the science now known as fluid dynamics and aerodynamics, with a wide variety of glyph tests that are not very scientific and not very successful as well.


Question: Who uses the Wind Tunnel tool?

Aerodynamics

In 1889, Charles Renard, a French aviation engineer, became the first to plausibly foresee the power required to maintain a hovering state. [15]


Question: Who uses the Wind Tunnel tool?

Aerodynamics

Renard and the German physicist, Hermann von Helmholtz, explored the charge of a bird's wing (a comparison of weights to the area of wing flutters), actually concluding that man would not be able to levitate on his own power simply by attaching wings to his arms.


Question: Who uses the Wind Tunnel tool?

Aerodynamics

Otto Lilienthal, following the work of Sir George Cayley, was the first to reasonably succeed with the flight of his launcher.


Question: Who uses the Wind Tunnel tool?

Aerodynamics

Lilienthal believed that a thin, curved air foil would produce a high lifting force and a low inhibitory force.


Question: Who uses the Wind Tunnel tool?

Aerodynamics

Octave Chanute gave great services to those interested in aerodynamics and glyphs by publishing a book containing all the research conducted in the world until 1893. [16]


Question: Who uses the Wind Tunnel tool?

Aerodynamics

Practical flight — early 20th century With the information contained in Chanute's book, personal assistance from Chanute himself, and the research done in the wind tunnel they created, the Wright Brothers gained enough knowledge of aerodynamics to fly an aircraft first on 17 December 1903.


Question: Who uses the Wind Tunnel tool?

Aerodynamics

The Wright Brothers' flight validated some of the aerodynamics theories and canceled some of the others.


Question: Who uses the Wind Tunnel tool?

Aerodynamics

Newton's inhibitory force theory was ultimately proven erroneous.


Question: Who uses the Wind Tunnel tool?

Aerodynamics

This first widely announced flight has sparked a more composed effort between aviators and scientists, guiding the way to modern aerodynamics.


Question: Who uses the Wind Tunnel tool?

Aerodynamics

At the time of the first flight, Frederick W. Lanchester, [17] Martin Wilhelm Kutta, and Nikolai Zhukovsky separately conceived theories linking the circulation of fluid flow to the lift force.


Question: Who uses the Wind Tunnel tool?

Aerodynamics

Kutta and Zhukovsky developed the theory of two-dimensional wings.


Question: Who uses the Wind Tunnel tool?

Aerodynamics

Expanding on Lanchester's work, Ludwig Prandtl was rewarded for his development of mathematics [18] that bolstered his theories of thin-air foils and lifting force lines, also corresponding to border layers.


Question: Who uses the Wind Tunnel tool?

Aerodynamics

Prandtl, a professor at the University of Göttingen, instructed many students who would be instrumental in the development of aerodynamics, such as Theodore von Kármán and Max Munk.


Question: Who uses the Wind Tunnel tool?

Aerodynamics

Design issues with progressively higher rates Compressibility are important factors in aerodynamics.


Question: Who uses the Wind Tunnel tool?

Aerodynamics

At low speeds, air compressibility is insignificant in relation to aircraft design, but as airflow approaches and exceeds the speed of sound, a number of new aerodynamic effects become important in aircraft design.


Question: Who uses the Wind Tunnel tool?

Aerodynamics

These effects, often several of them at a time, made it very difficult for WWII-era aircraft to reach speeds farther 800km/h (500mph).


Question: Who uses the Wind Tunnel tool?

Aerodynamics

Some minor effects include changes in airflow causing problems in control.


Question: Who uses the Wind Tunnel tool?

Aerodynamics

For example, P-38 Lightning with thick high lift wings have a particular problem in high-speed dives that cause nose-down conditions.


Question: Who uses the Wind Tunnel tool?

Aerodynamics

Pilots would enter a dive, and then find that they could no longer control the aircraft, which continued nose up until it crashed.


Question: Who uses the Wind Tunnel tool?

Aerodynamics

The problem was fixed by adding a “cover dive” under the wing which changed the center of pressure distribution so that the wing would not lose its lift.


Question: Who uses the Wind Tunnel tool?

Aerodynamics

Similar problems affected some models of the Supermarine Spitfire.


Question: Who uses the Wind Tunnel tool?

Aerodynamics

At high speeds the aileron could apply more torque than the Spitfire's thin wing could handle, and the entire wing would rotate in the opposite direction.


Question: Who uses the Wind Tunnel tool?

Aerodynamics

This meant that the aircraft would roll in the opposite direction to what the pilot intended, and caused a number of accidents.


Question: Who uses the Wind Tunnel tool?

Aerodynamics

Earlier models that were not fast enough for this were a problem, and so were not noticed until later Spitfires models such as the Mk.IX began to appear.


Question: Who uses the Wind Tunnel tool?

Aerodynamics

This was overcome by adding enough torsional rigidity to the wing, and fully healed when the Mk.XIV was introduced.


Question: Who uses the Wind Tunnel tool?

Aerodynamics

The Messerschmitt Bf 109 and Mitsubishi Zero had the opposite problem where the controls became ineffective.


Question: Who uses the Wind Tunnel tool?

Aerodynamics

At higher speeds the pilot simply could not move the controls because there was too much airflow over the control surface.


Question: Who uses the Wind Tunnel tool?

Aerodynamics

Aircraft would become difficult to maneuver, and at high enough speeds aircraft without these problems could out-turn them.


Question: Who uses the Wind Tunnel tool?

Aerodynamics

These problems were eventually resolved as jet aircraft reached transonic and supersonic speeds.


Question: Who uses the Wind Tunnel tool?

Aerodynamics

German scientists in World War II experimented with swept wings.


Question: Who uses the Wind Tunnel tool?

Aerodynamics

Their research was applied to the MiG-15 and F-86 Sabre and bombers such as the B-47 Stratojet used swept wings that delayed the onset of shock waves and reduced drag.


Question: Who uses the Wind Tunnel tool?

Aerodynamics

In order to maintain control near and above the speed of sound it was often necessary to use electrically operated tailplanes all flying (stabilators), or delta wings fitted with electric operated elevons.


Question: Who uses the Wind Tunnel tool?

Aerodynamics

Power operation prevents aerodynamic forces from impinging on the pilot's control input.


Question: Who uses the Wind Tunnel tool?

Aerodynamics

Finally, another common problem that fits into this category is vibrating aeroelasticity.


Question: Who uses the Wind Tunnel tool?

Aerodynamics

In some velocities the air flow over the control surface will become turbulent, and the control will begin to vibrate.


Question: Who uses the Wind Tunnel tool?

Aerodynamics

If the fluttering speed is close to the harmonics of the control movement, the resonants could break the control completely.


Question: Who uses the Wind Tunnel tool?

Aerodynamics

This is a serious problem on Zero.


Question: Who uses the Wind Tunnel tool?

Aerodynamics

When problems with poor control at high speeds were first encountered, they were addressed by designing a new style of control surface with more power.


Question: Who uses the Wind Tunnel tool?

Aerodynamics

However this introduced a new resonant mode, and a number of aircraft that were lost before these were discovered.


Question: Who uses the Wind Tunnel tool?

Aerodynamics

All these effects are often mentioned in conjunction with the term “compressibility”, but in the manner of speaking, they are incorrectly used.


Question: Who uses the Wind Tunnel tool?

Aerodynamics

From a strictly aerodynamic point of view, the term should refer only to those side effects arising as a result of changes in air flow from incompressible fluids (similar applies to water) to compressible fluids (acting as gases) as the speed of sound is approached.


Question: Who uses the Wind Tunnel tool?

Aerodynamics

There are two effects in particular, tensile wave and critical mach.


Question: Who uses the Wind Tunnel tool?

Aerodynamics

Wave drag a sudden increase in drag on the aircraft, caused by the water building in front of it.


Question: Who uses the Wind Tunnel tool?

Aerodynamics

At low speeds this air has time to “get out of the way”, guided by the air in front of it that is in contact with the aircraft.


Question: Who uses the Wind Tunnel tool?

Aerodynamics

But at the speed of sound this can no longer happen, and the air that previously followed the current, around the aircraft now hits directly.


Question: Who uses the Wind Tunnel tool?

Aerodynamics

The amount of power required to overcome this effect is considerable.


Question: Who uses the Wind Tunnel tool?

Aerodynamics

The critical mach is the speed at which some of the airflow passing through the wing of an aircraft becomes supersonic.


Question: Who uses the Wind Tunnel tool?

Aerodynamics

At the speed of sound in a raised manner generated changes dramatically, from those dominated by the Bernoulli Principle to the forces generated by shock waves.


Question: Who uses the Wind Tunnel tool?

Aerodynamics

Since the air at the top of the wing travels faster than at the bottom, due to the Bernoulli effect, with speeds approaching the speed of sound the air at the top of the wing will be accelerated for Supersonic.


Question: Who uses the Wind Tunnel tool?

Aerodynamics

When this happens the lift distribution changes dramatically, usually leading to a strong nose-down trim.


Question: Who uses the Wind Tunnel tool?

Aerodynamics

Since aircraft typically approach this speed only in a dive, pilots will report the aircraft trying to nose more into the ground.


Question: Who uses the Wind Tunnel tool?

Aerodynamics

Dissociation absorbs a lot of energy in a reversible process.


Question: Who uses the Wind Tunnel tool?

Aerodynamics

This greatly reduces the thermodynamic temperature of a hypersonic gas slowing down near a space vehicle.


Question: Who uses the Wind Tunnel tool?

Aerodynamics

In transition regions, where this dissociation pressure depends incomplete, both differential, constant pressure heat capacity and beta (volume/pressure differential ratio) will be greatly increased.


Question: Who uses the Wind Tunnel tool?

Aerodynamics

The latter has a pronounced effect on vehicle aerodynamics including stability.


Question: Who uses the Wind Tunnel tool?

Aerodynamics

Faster than sound — before the 20th century As planes began to travel faster, aerodynamicists realized that the density of air began to change as it came into contact with objects, leading to a division from fluid flow to incompressible and flow compressible regime.


Question: Who uses the Wind Tunnel tool?

Aerodynamics

In compressible aerodynamics, density and pressure both change, which is the basis for calculating the speed of sound Newton was the first to develop a mathematical model for calculating the speed of sound, but it was not true until Pierre-Simon Laplace accounted for the behavior of molecules gas and introduce heat capacity ratio.


Question: Who uses the Wind Tunnel tool?

Aerodynamics

The ratio of flow velocity to the speed of sound was named the Mach number after Ernst Mach, who was one of the first to investigate the supersonic properties of flow which included Schlieren photographic techniques for visualizing density changes.


Question: Who uses the Wind Tunnel tool?

Aerodynamics

William John Macquorn Rankine and Pierre Henri Hugoniot independently developed a theory for the nature of the flow before and after the shock wave.


Question: Who uses the Wind Tunnel tool?

Aerodynamics

Jakob Ackeret led early work on calculating lift and drag on supersonic airfoils.


Question: Who uses the Wind Tunnel tool?

Aerodynamics

Theodore von Karman and Hugh Latimer Dryden introduced the term transonic to describe the flow velocity around Mach 1 at which the attraction increases rapidly.


Question: Who uses the Wind Tunnel tool?

Aerodynamics

Due to the increased drag approaching Mach 1, aerodynamics experts and aviators disagreed on whether the supersonic aircraft was accomplished.


Question: Who uses the Wind Tunnel tool?

Aerodynamics

On September 30, 1935 an exclusive conference was held in Rome with the topic of high speed flight and the possibility of breaking sound barriers.


Question: Who uses the Wind Tunnel tool?

Aerodynamics

Participants included Theodore von Karman, Ludwig Prandtl, Jakob Ackeret, Eastman Jacobs, Adolf Busemann, Geoffrey Ingram Taylor, Gaetano Arturo Crocco, and Enrico Pistolesi.


Question: Who uses the Wind Tunnel tool?

Aerodynamics

Ackeret presented a design for supersonic wind tunnels.


Question: Who uses the Wind Tunnel tool?

Aerodynamics

Busemann gave a presentation on the need for aircraft with swept wings for high speed flight.


Question: Who uses the Wind Tunnel tool?

Aerodynamics

Eastman Jacobs, working for NACA, presented his airfoils optimized for the high subsonic speeds that led to several high-performance American aircraft during World War II.


Question: Who uses the Wind Tunnel tool?

Aerodynamics

Supersonic propulsion was also discussed.


Question: Who uses the Wind Tunnel tool?

Aerodynamics

The sound barrier was broken by using Bell X-1 aircraft twelve years later, thanks in part to the men.


Question: Who uses the Wind Tunnel tool?

Aerodynamics

By the time the sound barriers were broken, much of the knowledge of subsonic and low supersonic aerodynamics had matured.


Question: Who uses the Wind Tunnel tool?

Aerodynamics

The Cold War sparked an ever evolving line of high performance aircraft.


Question: Who uses the Wind Tunnel tool?

Aerodynamics

Computational fluid dynamics began as an attempt to solve the nature of flow around complex objects and has rapidly progressed to the point where the entire aircraft can be designed using computers, with wind tunnel tests followed by flight tests to confirm prediction computer.


Question: Who uses the Wind Tunnel tool?

Aerodynamics

With few exceptions, knowledge of aerodynamic hypersonics has matured between the 1960s and the decade.


Question: Who uses the Wind Tunnel tool?

Aerodynamics

Therefore, the goal of the aerodynamicist has shifted from understanding fluid flow behavior to understanding how vehicle engineers to interact precisely with fluid flow.


Question: Who uses the Wind Tunnel tool?

Aerodynamics

For example, while the behavior of hypersonic flow is understood, building an aircraft scramjet to fly at hypersonic speeds has seen very limited success.


Question: Who uses the Wind Tunnel tool?

Aerodynamics

Along with building successful scramjet aircraft, the desire to improve the aerodynamic efficiency of current aircraft and propulsion systems will continue to drive new research in aerodynamics.


Question: Who uses the Wind Tunnel tool?

Aerodynamics

However, there are still important problems in basic aerodynamic theory, such as in predicting the transition to turbulence, and the existence and uniqueness of solutions to the Navier—Stokes equations.


Question: Who uses the Wind Tunnel tool?

Aerodynamics

Aerodynamics Aerodynamics is a science that studies, examines and develops the characteristics of airflow movement around the surface of objects with a certain shape to determine the distribution of air pressure around the surface of the object and establish the force and moment it raises.


Question: Who uses the Wind Tunnel tool?

Aerodynamics

Importance of Aerodynamics: Examples of Historical examples If we look at history, it can be said that there are three historical periods with regard to the development of this aerodynamics, the first period started from aerodynamics in the ship of 1588, where when it was ships from Spain had a large size and had a large mass, in contrast the british ship had a small size and had a small mass as well.


Question: Who uses the Wind Tunnel tool?

Aerodynamics

In the second period in 1901 Wilbur and Orville wright designed a glider whose wing aerofoil design was based on aerodynamics data published in 1890 by Otto Lilienthal and Samuel Pierpont Langley, unfortunately the design did not come to fruition alias failed, in The same 1901 wright designed a wind tunnel that has a length of 6 feet and a cross-sectional area of 16 square inches then more than 200 different aerofoils and wings were tested or tested in the wind tunnel finally obtained aerodynamics data.


Question: Who uses the Wind Tunnel tool?

Aerodynamics

Based on these data wright redesigned his new glider in 1902, his aerofoils were more efficient and fruitless.


Question: Who uses the Wind Tunnel tool?

Aerodynamics

Since then there has been a very rapid development in the world of aviation, especially in terms of aerodynamics.


Question: Who uses the Wind Tunnel tool?

Aerodynamics

The next period is the third period on the development of rockets and space flight, high speed or supersonic flight became a warm talk in aerodynamics after the second world war, when aerodynamics was not seen next to the eye anymore in the sense that it had been appreciated in making various shapes of objects so that the object has a small drag.


Question: Who uses the Wind Tunnel tool?

Aerodynamics

In 1953 a hydrogen bomb was detonated by America and developed ICBMs (Intercontinental Ballistic Missile), the ICBMs were designed to be able to pass beyond the atmosphere which has a speed of 20,000 to 22,000ft/s, because of the speed then there was a new problem in the aerodynamics that is temperature.


Question: Who uses the Wind Tunnel tool?

Aerodynamics

In order for the heat generated to be minimal, we must make the flow laminer because the laminer flow will give up little heat when compared to the turbulent flow.


Question: Who uses the Wind Tunnel tool?

Aerodynamics

The problem of aerodynamic heat tackled by H Julian Allen, he introduced the concept of blunt reentry body.


Question: Who uses the Wind Tunnel tool?

Aerodynamics

At the time of entering the atmosphere vehicles have great kinetic energy because the speed is very high as well as the potential energy because the height increases to be higher than when at the surface of the earth, at the time of the earth, the vehicles have the kinetic energy tends to be small and the potential energy is zero, the energy is lost and turns into heat on the body/body and the heat of the air around the body.

Allen argued that if the huge atmospheric incoming energy could be discharged in the air stream then this not-so-great residual heat could be absorbed by the plane itself, while the way to create a hot one is air around the plane i.e. by making a strong shockwave, e.g. with a blunt tip, so that the shock wave can make the air heat around the plane.

Aerodynamic Force and Moment Although it may seem that the force acting on the plane looks very complex but the force can be divided into 2, namely the normal pressure distribution on the body surface and the second shear stress on the body surface.


Question: Who uses the Wind Tunnel tool?

Aerodynamics

Of these two forces lead to the resultant aerodynamic force R and the aerodynamic moment M. Dimensional analysis: Buckingham Pi's theorem of Buckingham Pi represents a method in reducing dimensional fickle numbers into numbers smaller than the group of dimensional groups.


Question: Who uses the Wind Tunnel tool?

Aerodynamics

This method allows the discovery of pi pi in the desired order without sorting against the free rank of Continuum Flow Type VS Free Molecular Flow In the continuum flow of molecules crashing continuously to the surface so that the body cannot distinguish molecular impact the molecule and the surface senses that the fluid is a continuum molecule, on the flow of free molecules if the molecular distance is large then the collision with the surface is felt not continuously and the body surface senses the collision of the molecule with the real Inviscid Flow VS Viscous Flow On The fluid flowing there is a displacement of mass, momentum, energy from somewhere to another place.

Aircraft Aerodynamics In principle, when the aircraft is airborne, there are 4 main forces acting on the aircraft, namely thrust force (thrust T), resistance (drag D), lift (liftL), and aircraft weight (W weight).


Question: Who uses the Wind Tunnel tool?

Aerodynamics

When the aircraft is cruising at constant speed and altitude, the four forces are in equilibrium: T = D and L = W. While at the time of the aircraft take off and landing, there is acceleration and deceleration which can be explained using Newton's Law II (the total force is equal to mass multiplied by acceleration).


Question: Who uses the Wind Tunnel tool?

Aerodynamics

At the time of take off, the aircraft experienced acceleration in both horizontal and vertical directions.


Question: Who uses the Wind Tunnel tool?

Aerodynamics

At this time, L must be greater than W, so too T is greater than D. Thus a large engine power is required at the time of take off.


Question: Who uses the Wind Tunnel tool?

Aerodynamics

Failure to take off can be caused by lack of engine power (due to various things: mechanical damage, human error, external interference, etc.), or system interference on the aircraft.


Question: Who uses the Wind Tunnel tool?

Aerodynamics

Behind the Flying An Aircraft Most commercial aircraft today use turbofan engines.


Question: Who uses the Wind Tunnel tool?

Aerodynamics

Turbofan comes from two words, namely turbine and fan.


Question: Who uses the Wind Tunnel tool?

Aerodynamics

Fan components are a differentiator between this engine and turbojet.


Question: Who uses the Wind Tunnel tool?

Aerodynamics

In turbojet engines, the outside air is compressed by the compressor until it reaches high pressure.


Question: Who uses the Wind Tunnel tool?

Aerodynamics

Further, the high-pressure air enters the combustion chamber to be mixed with fuel (avtur).


Question: Who uses the Wind Tunnel tool?

Aerodynamics

The combustion of such fuel air will increase the temperature and pressure of the working fluid.


Question: Who uses the Wind Tunnel tool?

Aerodynamics

This high-pressure fluid is further passed through the turbine and out at the nozzle at very high speed.


Question: Who uses the Wind Tunnel tool?

Aerodynamics

The difference in the velocity of the incoming air and outgoing fluid from the engine imparts the thrust force T (Newton's Law III: Action and Reaction).


Question: Who uses the Wind Tunnel tool?

Aerodynamics

This T thrust force is utilized to move in a horizontal direction and is partially converted by the aircraft wing into an L lift force. The fan on the turbofan engine serves to provide additional rate of air entering the engine via a water bypass.


Question: Who uses the Wind Tunnel tool?

Aerodynamics

This fresh air will meet with a mixture of fuel air that has burned at the outer end of the engine.


Question: Who uses the Wind Tunnel tool?

Aerodynamics

One advantage of using a turbofan is that he is able to muffle the noise of the noise on the turbojet.


Question: Who uses the Wind Tunnel tool?

Aerodynamics

But because turbofans have a relatively complex arrangement of components, this type of engine is very susceptible to FOD (Foreign Object Damage) interference and ice formation inside the engine.


Question: Who uses the Wind Tunnel tool?

Aerodynamics

The entry of FOD (like a bird) into the engine could cause a fatal event on the aircraft.


Question: Who uses the Wind Tunnel tool?

Aerodynamics

Wings: Turning T into L To date, there are at least 3 accepted explanations for the phenomenon of the appearance of lifting forces on wings: Bernoulli's principle, Newton's Law III, and the Coanda effect.


Question: Who uses the Wind Tunnel tool?

Aerodynamics

The wing of the aircraft has a unique transverse cut contour: the airfoil.


Question: Who uses the Wind Tunnel tool?

Aerodynamics

In airfoils, the upper surface is slightly curved forming a convex curve, while the lower surface is relatively flat.


Question: Who uses the Wind Tunnel tool?

Aerodynamics

When a group of airshits the contour of this airfoil, then it is possible that the upper air will have a higher velocity than the bottom: this is due to the fact that the upper air must pass a longer distance (the upper surface of the airfoil is convex) than the air of the section down.


Question: Who uses the Wind Tunnel tool?

Aerodynamics

Bernoulli's principle states that the higher the fluid velocity (for relatively equal altitudes), then the pressure will shrink.


Question: Who uses the Wind Tunnel tool?

Aerodynamics

Thus there will be a pressure difference between the lower and upper air of the wing: this is what creates the lifting force L. This explanation with Bernoulli's principle still reaps the pros of cons; but this explanation is what Boeing uses to explain the principle of lift force.


Question: Who uses the Wind Tunnel tool?

Aerodynamics

Explanations using Newton's Law III emphasize the principle of momentum change when air is deflected by the underside of the aircraft wing.


Question: Who uses the Wind Tunnel tool?

Aerodynamics

From the principle of action of the reaction, there arises a force on the underside of the wing that is equal to the force that the wing exerts to deflect air.


Question: Who uses the Wind Tunnel tool?

Aerodynamics

While the explanation uses the Coanda effect emphasizes the turning of the air contour flowing at the top of the wing.


Question: Who uses the Wind Tunnel tool?

Aerodynamics

The convex top of the aircraft's wings forces air to follow those contours.


Question: Who uses the Wind Tunnel tool?

Aerodynamics

Such air contour defection is possible due to the presence of a low pressure region on the top of the aircraft wing (or by another explanation: that air contour defection creates a low pressure area).


Question: Who uses the Wind Tunnel tool?

Aerodynamics

Such pressure differences create force differences that give rise to the lift force L. Although there is no official consensus yet on the most accurate mechanism to explain the emergence of the lifting force phenomenon, clearly the aircraft wing managed to convert part of the engine's T thrust force to L lift force. Aircraft Motion Control Aircraft has the ability to move in three axes, namely pitch, roll, and yaw.


Question: Who uses the Wind Tunnel tool?

Aerodynamics

The motion of the rise and fall of the aircraft's nose is controlled by elevators, the motion of the rise and fall of the aircraft's wings is controlled by the ailerons, while the motion of turning in the horizontal plane is controlled by the rudder located in the fin (fin) of the aircraft.


Question: Who uses the Wind Tunnel tool?

Aerodynamics

In addition, on the back of the wing there is also a flap that serves to increase the lifting force at the time of take off or reduce the lifting force during landing (air brake).


Question: Who uses the Wind Tunnel tool?

Aerodynamics

At the time of cruising (cruise) this flap will fit inside the wing to reduce the aircraft's D retardant force.


Question: Who uses the Wind Tunnel tool?

Aerodynamics

Most aircraft accidents at the time of take off occur due to engine malfunctions that arise due to various causes.


Question: Who uses the Wind Tunnel tool?

Aerodynamics

Failure of the engine function can be caused due to damage to the engine components itself, damage to the area near the engine that impacted on the engine, leakage and burning of the fuel tank, or damage to the aircraft control system, or human error.


Question: Who uses the Wind Tunnel tool?

Although the aerodynamics in rally cars are not very significant, the installation of such a device is not indiscriminate.


Question: Who uses the Wind Tunnel tool?

All there are counts and functions.


Question: Who uses the Wind Tunnel tool?

Aerodynamics

Moreover, this is also regulated by the FIA International Automotive Agency through its strict regulations.


Question: Who uses the Wind Tunnel tool?

Aerodynamics

Mamang recognized aerodynamics in rally cars were not as important as in Grand Prix racing cars.


Question: Who uses the Wind Tunnel tool?

Aerodynamics

Moreover, the shape of the rally car that now follows the shape of the original, mass-produced car.


Question: Who uses the Wind Tunnel tool?

Aerodynamics

Not like F1 cars or whatnot.


Question: Who uses the Wind Tunnel tool?

Aerodynamics

But that doesn't mean rally cars ignore aerodynamics issues.


Question: Who uses the Wind Tunnel tool?

Aerodynamics

The body shell and aerodynamics of the WRC cars (WRCar) used today are very different from the 1908-s-era and 1990s-era WRCar. That is due to the FIA regulations governing the weight of vehicles and the dimensions of spoilers allowed to wear have changed.


Question: Who uses the Wind Tunnel tool?

Aerodynamics

In addition, people's understanding of aerodynamic functions in WRCar has improved as technology advances.


Question: Who uses the Wind Tunnel tool?

Aerodynamics

That is, the firmer the pace of the car, then the car needs good and precise aerodynamic support.


Question: Who uses the Wind Tunnel tool?

Aerodynamics

Of the overall aerodynamics of the WRCar make the front and rear, the most noticed is the front.


Question: Who uses the Wind Tunnel tool?

Aerodynamics

The front is the part of the car that first cleaves angina when the car travels at high speeds.


Question: Who uses the Wind Tunnel tool?

Aerodynamics

That's why to create balance on the front, WRCar mechanics are most concerned about the bumper.


Question: Who uses the Wind Tunnel tool?

Aerodynamics

The level of aerodynamics on the part of the WRCar is vital.


Question: Who uses the Wind Tunnel tool?

Aerodynamics

Because, FIA applies regulations for engine cooling systems.


Question: Who uses the Wind Tunnel tool?

Aerodynamics

If following the FIA rules, the cooling system has not been able to work maximally to cool the engine.


Question: Who uses the Wind Tunnel tool?

Aerodynamics

Hence the car must rely on air as a cooling auxiliary device.


Question: Who uses the Wind Tunnel tool?

Aerodynamics

The trick is by modifying the shape of the bumper as much as possible.


Question: Who uses the Wind Tunnel tool?

Aerodynamics

A good bumper shape with the right level of aerodynamics can help cool the radiator and intercooler.


Question: Who uses the Wind Tunnel tool?

Aerodynamics

In addition it helps bypass (bypass) angina passing through the engine room.


Question: Who uses the Wind Tunnel tool?

Aerodynamics

Air volume and air velocity entering from the front can serve to cool the intercooler.


Question: Who uses the Wind Tunnel tool?

Aerodynamics

As a result, the biased mounted intercooler is larger in size.


Question: Who uses the Wind Tunnel tool?

Aerodynamics

There is another device located near the bumper, namely air conduct, which is located at the bottom of the bumper.


Question: Who uses the Wind Tunnel tool?

Aerodynamics

This device helps cool the brake system so that the temperature is maintained.


Question: Who uses the Wind Tunnel tool?

Aerodynamics

Although the brakes are used many times in high-speed circumstances, the system can work well.


Question: Who uses the Wind Tunnel tool?

Aerodynamics

To obtain a larger cooling area for the engine, the fog lamp mounted on the bumper must be small.


Question: Who uses the Wind Tunnel tool?

Aerodynamics

The shape of the house fog lamp was also hemispherical jarena proven to help the level of aerodynamics mabil.


Question: Who uses the Wind Tunnel tool?

Aerodynamics

The bumpers used on the WRCar are wide.


Question: Who uses the Wind Tunnel tool?

Aerodynamics

Its function is to adjust the width of the vehicle so that the air resistance posed by the front can be minimized.


Question: Who uses the Wind Tunnel tool?

Aerodynamics

Usually to know whether or not the way the bumper works, the car must go through the pangujian in the wind tunnel (tunnel angina) so that the aerodynamic speed is needed.


Question: Who uses the Wind Tunnel tool?

Aerodynamics

The basic material for making bumpers is made of flexible soft carbon.


Question: Who uses the Wind Tunnel tool?

Aerodynamics

Even this is shatterproof and not easy to deform if the car collides.


Question: Who uses the Wind Tunnel tool?

Aerodynamics

Long ago before this material was used, WRCar bumpers were made of rubber.


Question: Who uses the Wind Tunnel tool?

Aerodynamics

After the front, stone modifications are made for the rear.


Question: Who uses the Wind Tunnel tool?

Aerodynamics

Usually rear modifications are done to balance the aerodynamics at the front.


Question: Who uses the Wind Tunnel tool?

Aerodynamics

Generally the most noticed at the rear is the rear deck spoiler.


Question: Who uses the Wind Tunnel tool?

Aerodynamics

The shape of this part is always capricious according to FIA regulations.


Question: Who uses the Wind Tunnel tool?

Aerodynamics

Currently applicable regulations require a smaller rear deck spoiler.


Question: Who uses the Wind Tunnel tool?

Aerodynamics

In order for the bias to adjust to the new regulation, a number of WRC cars rely on the number of wings.


Question: Who uses the Wind Tunnel tool?

Aerodynamics

From the result of the addition, the down force of the rear of the car is increasingly gripping.


Question: Who uses the Wind Tunnel tool?

Aerodynamics

But there is also a vertical rectifying plate (vertical plate on the rear wing).


Question: Who uses the Wind Tunnel tool?

Aerodynamics

It aims to improve the stability of the vehicle at medium speeds in the corners when the vehicle is sliding.


Question: Who uses the Wind Tunnel tool?

Aerodynamics

With this tool, the car will not be out when looking at high speed Terminology related to incompressible and incompressible flow regimes produce many related phenomena, such as boundary layers and turbulence.


Question: Who uses the Wind Tunnel tool?

Aerodynamics

Boundary Layer The concept of boundary layer is important in many aerodynamic issues.


Question: Who uses the Wind Tunnel tool?

Aerodynamics

The viscosity and friction of liquids in air are approximated as significant only in this thin layer.


Question: Who uses the Wind Tunnel tool?

Aerodynamics

This principle makes aerodynamics that much more mathematically submissive.


Question: Who uses the Wind Tunnel tool?

Aerodynamics

Turbulence In aerodynamics, turbulence is characterized by chaotic, stochastic property changes in the flow.


Question: Who uses the Wind Tunnel tool?

Aerodynamics

These include low-momentum diffusion, high-momentum convection, and rapid variations of pressure and velocity in space and time.
