高超声速飞行器单周期飞行轨迹优化研究

Optimization on a Period of Flying Orbit of Hypersonic Vehicle

高超声速飞行器的初始质量和起始角度的大小对飞行器的飞行轨迹有较大影响,也影响飞行器的其它参数设计。针对飞行器的飞行情况将飞行轨迹划分为6个状态,并建立3个模型进行分析,然后使用改进的粒子群算法,分别对初始质量、起始角度和水平位移的关系进行了测试,并参照测试结果对飞行轨迹进行了整体优化研究。最后通过算例进行了测试和分析,验证了该方法的合理性和有效性。

The magnitude of the original quality and original angle of hypersonic vehicle can influence flying orbit and other design--parameters greatly. Firstly, according to flying process, the flying orbit was divided into six states analyzed by three models. Then a modified particle swarm optimization （PSO） algorithm was used to test the relationship among original quality, original angle and level distance. Referring to the test result, optimization research on a period of flying orbit of hypersonic vehicle was performed. Finally, the method has been successfully used and validated its rationality and validity by testing and analyzing the example.
