为解决前缘钝化后由于外形的变化引起周围流场改变,导致激波形状发生变化而影响飞行器气动特性的问题,对前缘钝化后的吸气式高超声速飞行器气动特性进行了研究。对比分析了前缘钝化对吸气式高超声速飞行器气动特性的影响,得出了吸气式高超声速飞行器气动性能参数随着钝化半径的变化规律。研究结论可为乘波构型的高超声速飞行器一体化设计提供一定的依据。
In order to solve the problem that the shape of the shock wave changes and affect the aerodynamic characteristics of the aircraft due to the change of the surrounding flow field caused by the change of shape after the leading edge passivation, the aerodynamic characteristics of the aspirated hypersonic vehicle after the leading edge passivation are studied. The influence of leading edge passivation on the aerodynamic characteristics of the aspirated hypersonic vehicle was analyzed and compared. The aerodynamic performance parameters of the aspirated hypersonic vehicle were obtained as a function of the passivation radius. The conclusion of the research can provide a certain basis for the integrated design of the hypersonic vehicle with the wave structure.
