摘　　要：为了给高超声速轨迹预测问题提供先验知识,研究了面向轨迹预测的高超声速飞行器气动性能分析问题。首先,简要介绍了高超声速再入滑翔飞行器的基本性能,从拦截的角度分析了对其滑翔段进行轨迹预测的必要性。其次,以HTV-2为例,采用斜激波理论、活塞理论、Prandtl-Meyer方程及粘性力工程计算方法对临近空间高超声速环境下飞行器的受力情况进行了分析建模。然后,对目标机动性能进行了仿真分析,仿真结果与相关文献报道较一致,证明了建模仿真方法的可行性。最后,基于以上建模仿真,给出了一组适用于临近空间高超声速飞行器滑翔段目标跟踪和轨迹预测的气动参数,并进行了仿真验证,为下一步研究基于拦截的高超声速飞行器轨迹预测提供了理论基础和方法指导。In order to provide the prior knowledge for the trajectory prediction of hypersonic vehicle,trajectory prediction oriented aerodynamic performances analysis of hypersonic vehicles was researched.Firstly,the basic performances of the hypersonic reentry-glide vehicle were introduced,and the necessity of trajectory prediction for intercepting hypersonic vehicles was analyzed.Secondly,take HTV-2 as an example,its aerodynamic force and maneuvering performances were simulated through oblique-shock theory,piston theory and Prandtl-Meyer flow.The simulation results are identical to that in the references,which demonstrate the validity of the simulation method.What＇s more,in order to make the trajectory prediction possible,a new set of aerodynamic parameters was proposed based on the simulations of aerodynamic force above,which provides theoretical basis and reference for trajectory prediction of hypersonic vehicles.
