近空间高超音速滑翔机的滑翔特性研究

Gliding characteristics for near-earth space hypersonic glider

解析估算了近空间高超音速滑翔机的平衡滑翔初始点,以及其初始状态与滑翔能力的关系;数字仿真分析了其初始值与飞行距离、动压、相对驻点热流、相对总加热量、马赫数等的关系;给出了有关近空间内滑翔数千公里的滑翔特性的分析结论,给出了进入滑翔状态和退出滑翔的方法。

Initial point of equilibrium glide, as well as the relationship between initial condition and gliding ability is analytically calculated for near-earth space hypersonic glider. Numerical simulation analyzes the relationships between its initial value and other values including flight distance, the dynamic pressure, the relative heat flow at standing point, the relative total calories, Mach number and so on. Conclusions are given for thousands of kilometers gliding characteristics in near-earth space, and the method for entering and quitting gliding status is also proposed.
