高超声速滑翔飞行器弹道仿真分析

rajectory Simulation Analysis of Hypersonic Boost-glide Vehicle

摘要:

针对临近空间高超声速助推滑翔飞行器弹道轨迹预测,以高超声速助推滑翔飞行器为研究对象进行了纵平面运动轨迹建模、气动参数估计及攻角模型设计。不同滑翔初始状态下的弹道仿真结果表明:滑翔初始运动高度越高,跳跃幅度越大;滑翔初始运动速度越大,滑翔时间越长。通过研究加深了对高超声速飞行器运动特性的认识,为弹道预报、轨迹规划与制导系统设计等任务提供了参考。

Abstract:

Aiming at the trajectory prediction of hypersonic boost-glide vehicle in nearspace, the longitudina plane motion trajectory model, aerodynamic parameters estimationand angle of attack model design of hypersonic boost-glide vehicle are carried out, Thetrajectory simulation results of different initial gliding states show that the higher thestarting height of glide is, the larger the jump amplitude is. The greater the starting speed otglide is, the longer the glide time is. The research deepens the cognition of the motionharacteristics of hypersonic vehicle, and provides a reference for the mission of trajectoryprediction，trajectory planning and guidance system design.
