Numerical Study of Attack Angle Characteristics for Integrated Hypersonic Vehicle

Institute of Aerospace & Material Engineering, National University of Defense Technology, Changsha 410073, P. R. China

摘要

摘要: 采用二维耦合隐式NS方程和标准k-ε湍流模型，对采用Hark形头部的一体化高超声速飞行器在进气道关闭、发动机通流和发动机点火工况下的攻角特性进行了数值仿真研究．探索了可变攻角情况下，飞行器各部件对飞行器整体气动-推进性能的贡献程度A·D2结果表明，在3种不同的工作状态下，飞行器都是纵向静稳定的，足够大的升阻比可以满足飞行器飞行要求，同时，对发动机型面及机身上壁面的改进有利于进一步满足飞行器对气动-推进性能的要求．

Abstract: Two dimension coupled implicit NS equations and standard k epsilon viscous models were used to simulate the angle of attack characteristics of integrated hypersonic vehicle with hark head configuration under three kinds of working conditions,i.e.inlet cut off,engine through flow,engine ignition.The influence of each component on the aero propulsive performance of vehicle was dis cussed.It is concluded that the longitudinal static stability of vehicle is good;it has enough lift to drag ratio to satisfy the flying requirement of the vehicle.At the same time,it is very important to change the configurations of engine and upper surface of airframe to improve the aero propulsion of the vehicle.
