Query: Penetration trajectory optimization for the hypersonic gliding vehicle
  encountering two interceptors   The penetration trajectory optimization problem for the hypersonic gliding
vehicle (HGV) encountering two interceptors is investigated. The HGV
penetration trajectory optimization problem considering the terminal target
area is formulated as a nonconvex optimal control problem. The nonconvex
optimal control problem is transformed into a second-order cone programming
(SOCP) problem, which can be solved by state-of-the-art interior-point methods.
In addition, a penetration strategy that only requires the initial
line-of-sight angle information of the interceptors is proposed. The convergent
trajectory obtained by the proposed method allows the HGV to evade two
interceptors and reach the target area successfully. Furthermore, a successive
SOCP method with a variable trust region is presented, which is critical to
balancing the trade-off between time consumption and optimality. Finally, the
effectiveness and performance of the proposed method are verified by numerical
simulations.
