Question: Who created the rotor Plane?

helicopter

When the airflow generated by the engine flows backwards and through the main wing then that airflow is split.


Question: Who created the rotor Plane?

helicopter

The air flow flowing over the upper wing surface is more intense than the air flow hitting the lower wing surface.


Question: Who created the rotor Plane?

helicopter

But the air pressure flowing heavily above the upper wing surface, is relatively smaller than the air pressure on the lower wing surface, which is precisely less heavy flow.


Question: Who created the rotor Plane?

helicopter

It is this difference in air pressure that causes the aircraft's wings to lift upwards.


Question: Who created the rotor Plane?

helicopter

To imagine how big that lift force is, it is theorized to mention that a 2.5 ounce per square inch difference in air pressure can produce a lift force of 20 pounds per square foot (1 foot = 20cm).


Question: Who created the rotor Plane?

helicopter

Calculable, if the wing area of the aircraft is 1000 square feet then the resulting lift force will reach 10 tons.


Question: Who created the rotor Plane?

helicopter

In helicopters, the wing function is replaced by a propeller whose each propeller is despite being smaller in size than a regular aircraft wing, but when rotated, the curva is relatively the same as the aircraft wing.


Question: Who created the rotor Plane?

helicopter

To obtain the lifting force, the rotor blades must be directed at a certain position so as to form a large coming angle.


Question: Who created the rotor Plane?

helicopter

The principle is the same as for fixed-winged aircraft, on helicopters there are two large styles that give each other influence.


Question: Who created the rotor Plane?

helicopter

The forward-moving air flow of the propeller presses the propeller so that the blades of the propeller are pushed back to the rear producing a small lift force.


Question: Who created the rotor Plane?

helicopter

But when the airflow moves rapidly past the top and bottom of the blades of the propeller, the large air pressure between the propellers will automatically expand to the entire lower pressure surface, causing the propeller to be pushed upwards and the helicopter lifted.


Question: Who created the rotor Plane?

helicopter

Keep in mind, even if the blades of the propeller are only a few sheets, but in a fast rotating state, it will form a flat surface and the air pressing it upwards accumulates a large pressure that eventually produces a large lifting force.


Question: Who created the rotor Plane?

helicopter

This principle is the same as the function of the propeller in turboprop-engined aircraft and the same as the “citiran” of the children's toy.


Question: Who created the rotor Plane?

helicopter

Some helicopters used in the war, such as the Mi-26 Hind for example were fitted with a small wing called a canard, its first function to lighten the load of the main rotor and the second to increase the speed rate and extend the cruising range.


Question: Who created the rotor Plane?

helicopter

Other functions are as arms hangers, missiles and others.


Question: Who created the rotor Plane?

helicopter

By adding these short wings, then the functional differences between fixed aircraft with helicopters became vague.


Question: Who created the rotor Plane?

helicopter

Fixed-winged aircraft also exist capable of fly-landing vertically (Vertical Take-off Landing/VTOL).


Question: Who created the rotor Plane?

helicopter

Contonya, Harrier of the Sea Harrier type or AV-8 Harrier.


Question: Who created the rotor Plane?

helicopter

The advantages of fixed-wing aircraft, especially about flying because aircraft of this type have a wide platform so it is relatively more stable during flight.


Question: Who created the rotor Plane?

helicopter

About flying it, it's a matter of regulating the rudder bolster on the wings and the upright and flat stabilizer that is on the tail.


Question: Who created the rotor Plane?

helicopter

But on Helicopters is not the case.


Question: Who created the rotor Plane?

helicopter

When the blades of the propeller his rotor generates its own rotor lifting force works moving the air above it down as much as much.


Question: Who created the rotor Plane?

helicopter

At that time the weight of the air moved reduced the weight of the helicopter so that the helicopter lifted off.


Question: Who created the rotor Plane?

helicopter

And when the helicopter is lifted, it means that there is a balance of weight between the air being moved from top to bottom and the weight of the helicopter.


Question: Who created the rotor Plane?

helicopter

To operate the helicopter there is a steering gear commonly calledcollective pitch and cyclic pitch respectively serving as a regulator of the lift force and thruster of the helicopter to drive forward.


Question: Who created the rotor Plane?

helicopter

It's so simple how it works, but transforming it in a technology is really a tricky job.


Question: Who created the rotor Plane?

helicopter

Tail rotor is the case with the rotor configuration, not just being able to rotate and fly and float.


Question: Who created the rotor Plane?

helicopter

Because the propeller rotated will always cause rotation power called the general term torque.


Question: Who created the rotor Plane?

helicopter

To eliminate or counteract the rotary force that could cause the helicopter body to rotate, it is necessary to install an antitorque.


Question: Who created the rotor Plane?

helicopter

This antitorque can be a tail rotor or a tail rotor mounted on the tail of the aircraft which also serves as a rudder.


Question: Who created the rotor Plane?

helicopter

This configuration can be seen in helicopters generally such as the Bell-412, Bell-205 or UH-1 Huey, or NBO-105, and AS-330 Puma or AS-335 Super Puma, AH-64 APACHE or Mi-24 HIND.


Question: Who created the rotor Plane?

helicopter

Selin uses tail rotor, there are still some other designs.


Question: Who created the rotor Plane?

helicopter

For example those using tandem systems such as those used on Boeing CH-47 Chinook or CH-46 Sea Knight helicopters.


Question: Who created the rotor Plane?

helicopter

The two rotors are together large, respectively, placed in front and behind the helicopter body.


Question: Who created the rotor Plane?

helicopter

Both are symmetrical but have opposite-directional turns.


Question: Who created the rotor Plane?

helicopter

He meant to mutually negate the effect the spin inflicted on each other, intermesh in his popular parlance.


Question: Who created the rotor Plane?

helicopter

Another way is to egg-beater configuration.


Question: Who created the rotor Plane?

helicopter

Such a design build configuration is used on the Russian-made Ka-25 Kamov helicopter or Kaman HH-43 Husky.


Question: Who created the rotor Plane?

helicopter

Both vanes of equal magnitude were laid in one shaft, separated from each other where one was placed over the other rotor.


Question: Who created the rotor Plane?

helicopter

The two rotate in opposite directions.


Question: Who created the rotor Plane?

helicopter

It means to eliminate the effect of a round or torque.


Question: Who created the rotor Plane?

helicopter

In addition to the above three ways, it is also made configuration without a tail rotor.


Question: Who created the rotor Plane?

helicopter

This helicopter is called NOTAR (No Tail Rotor) it has a slightly different system to the existing system where it utilizes hot gas bursts from the main engine which is channeled through the tail tube.


Question: Who created the rotor Plane?

helicopter

An example is the MD-902 Explorer helicopter.


Question: Who created the rotor Plane?

helicopter

Active Rotor or Tilt Rotor and Active Wing or Tilt Wing Live takeoff and landing ala helicopter but with the character of flying kinds of fixed winged aircraft is a concept embraced by this type of helicopter.


Question: Who created the rotor Plane?

helicopter

The easiest way is to combine the working concept of a helicopter aircraft with a fixed-winged aircraft in one form.


Question: Who created the rotor Plane?

helicopter

The principle of work is technically when the main rotor is directed upwards then the vertical movement performed by the helikoter can be performed while when the rotor is directed forward or backward (as a pursher or thruster) then a flying character such as a plane can still be obtained.


Question: Who created the rotor Plane?

helicopter

This kind of rotor movement does not need to engage the wing.


Question: Who created the rotor Plane?

helicopter

Actually, the development of this active rotor is still covered with tightness, the problem is that the system could have been called a fixed-winged aircraft because it has a fairly large wing, as well as having an aircraft tail configured with a regular fixed-wing aircraft.


Question: Who created the rotor Plane?

helicopter

Finally, this concept is called the hybrid concept.


Question: Who created the rotor Plane?

helicopter

An example of this helicopter is the V-22 Osprey.


Question: Who created the rotor Plane?

helicopter

In addition to the active rotor concept, there is also the concept of an active wing, where the driven is not the rotor as in the active rotor but the wing of the aircraft.


Question: Who created the rotor Plane?

helicopter

While the machine remains in its position.


Question: Who created the rotor Plane?

helicopter

An example of this helicopter is the TW-68 designed by Ishida Corporation, Japan, This design is touted as having a more compact draft compared to the active rotor only unfortunately its sustainability is not so sound.


Question: Who created the rotor Plane?

Lontar Seats on Helicopters Compared to ordinary aircraft, especially fighter aircraft, helicopter aircraft are generally not equipped with jump seats.


Question: Who created the rotor Plane?

helicopter

This is due to problems facing helicopter rotors when launching the skip seat at once generally the helicopter flies lower so it is more vulnerable.


Question: Who created the rotor Plane?

helicopter

Nevertheless on Russian helicopters, the Kamov Ka-50 Hokum that uses specially designed lontar seats such as the Zvesda K-37-800.


Question: Who created the rotor Plane?

helicopter

The work step is that when the jump seat is activated, then the rotor is detonated and detached from the seat, then the two upper sides of the cockpit glass open and the active towing rocket that pulls the pilot and his seat out of the heli body.


Question: Who created the rotor Plane?

helicopter

Although it is considered complicated, future helicopters will be equipped with a flying seat. In fact, helicopter travel into a known form at this time takes quite a long period of time.


Question: Who created the rotor Plane?
