高超声速滑翔飞行器弹道特性分析

Trajectory Characteristic of Hypersonic Gliding Vehicle

高超声速滑翔飞行器是当前研究热点方向之一,平衡滑翔和跳跃滑翔是两种典型的飞行模式。针对两种飞行模式展开研究,在平衡滑翔弹道分析的基础上,利用数值方法研究初始高度、速度及速度倾角偏离平衡滑翔状态时对弹道性能的影响,分析了跳跃弹道形成的原因,通过无量纲速度-高度图初步揭示了平衡滑翔和跳跃滑翔之间的联系。

Hypersonic gliding vehicle is an important research direction at present.Equilibrium gliding and skip gliding are two typical flight modes.This paper focuses on the relation between the two modes.Based on the analysis of equilibrium gliding,the initial height,velocity and the effect of flight path angle deviation to the performance of the trajectory are analyzed by using numerical methods.The formation of skip gliding trajectory are analyzed,the non-dimensional velocity-height figure reveals the relationship between equilibrium gliding and skip gliding.
