| 摘要: |
| 乘波体是一类典型的高超声速飞行器外形，它具有较高的升力及升阻比特性。建立了一套基于激波装配法的乘波体设计方法，该方法采用激波装配法获得精确激波位置，同时引入导波体的概念，通过设计导波体的构型来决定激波面的形状，引入导波体构型参数。通过改变导波体俯视外形前后锥角度、前后体长度比、侧视外形表面后锥角度等参数，比较其对最终乘波体气动特性的影响，并分析了这些参数改变对乘波体气动特性影响的内在机制，为工程化乘波体设计提供理论指导。 |

| Abstract: |
| Wave-rider is a typical high-speed vehicle configuration, which is higher than ordinary vehicle in terms of the ratio of lift to drag(L/D). Based on shock fitting method, a new design method of wave rider is found, which introduces shock generating body(SGB) and gets the accurate outer shock surface. The configuration of SGB is designed to define the outer shock surface. The configuration parameters of SGB including the front/rear cone angles in overlook side, the ratio of fore body length to rear body length, and the below angles of rear cone in overlook view are studied at the effect on the aerodynamic characteristics of wave rider. The mechanism behind the effect is analyzed, which guides the design of engineering wave rider. |
