多约束条件下高超声速导弹再入轨迹优化
Re-entry Trajectory Optimization for Supersonic Missile Considering Multiple Constraints
摘要
Abstract
To study the re-entry trajectory optimization characteristics of supersonic missile with multiple constraints, the trajectory multi-phase optimization method was proposed. The re-entry trajectory was classified as the decline phas,jump cruise phase and swoop attack phase. The kinetic model,the pneumatic model and the atmosphere density model were built. The trajectory simulation was carried out using maximum end-speed and minimum heat as target function based on hp adaptive pseudospectral method and Gauss pseudospectral method, and the constraints of normal load, dynamic pressure, head point heat, etc, were considered. The simulation results indicate that the computation time is reduced,and the complexity is also reduced.关键词
