The invention provides a design method for a low-speed friendly waverider configuration of a wedge-derived plane shape. According to the method, under the condition that an incoming flow Mach number and a shock wave angle are given, a low-speed friendly plane shape curve of a given target waverider configuration is projected to a plane shock wave, and then a plane wedge-guided shock wave flow field is solved for streamline tracking, so that customization of the plane shape of the waverider configuration is realized; and the design of a low-speed friendly waverider configuration with better low-speed performance is obtained. The waverider configuration generated through the method is good in waverider characteristic, the lift-drag ratio reaches a very high level while a high plot ratio is maintained, meanwhile, the uniformity of a flow field after waverider surface waves is very high, the designed actual shock wave outlet position is completely consistent with the theoretical shock wave outlet position, integrated design of a propelling system is very facilitated, and the method is suitable for popularization and application. The method can be applied to the field of aerodynamic configuration design of hypersonic aircrafts.

    本发明提出了一种楔导定平面形状低速友好型乘波构型设计方法。该方法在给定来流马赫数和激波角的情况下,通过将给定目标乘波构型的低速友好型平面形状曲线投影至平面激波上,继而求解平面楔导激波流场进行流线追踪,实现对乘波构型平面形状的定制,得到低速性能更好的低速友好型乘波构型的设计。利用该方法生成的乘波构型乘波特性良好,在维持一个较高容积率的同时,升阻比达到了很高的水平,同时,乘波面波后流场均匀度很高,设计得到的实际激波出口位置与理论激波出口位置完全一致,对推进系统的一体化设计十分有利,本发明能够应用于高超声速飞行器的气动外形设计领域。
