| 摘 要： | 乘波体构型应用于吸气式高超声速飞行器设计主要有两大优势:一是可以高效地捕获预压缩后的气流；二是通过优化，可以实现飞行器的高升阻比性能设计。基于这两个优势，乘波概念应用于高超声速飞行器机体/进气道气动一体化设计可分为两大类:乘波前体/进气道一体化设计和乘波机体/进气道一体化设计，前者主要利用乘波体高效捕获预压缩气流的特性，而后者则同时利用乘波设计的两个优势。本文总结了国内外学者将乘波概念应用于机体/进气道一体化设计的两大类方法，对其进行了较为细致的分类，归纳总结出"通过设计基准流场进行流向设计、应用吻切理论或几何拼接方法进行展向设计"的总体设计思路，分析了今后的研究发展趋势。

| Abstract: | As a waverider can possess high lift-to-drag ratio characteristics as well as an ideal pre-compression surface of the inlet system, it has become one of the most promising designs for air-breathing hypersonic vehicles. There are two classes of general methodologies for utilizing the waverider concept in a hypersonic vehicle design. In the first class, the waverider is used only as the forebody of a vehicle, and it behaves as the pre-compression surface to efficiently provide the inlet system with the required compression flow field. In the second class, in order to take advantage of the waverider's high lift-to-drag ratio characteristics as well as the ideal pre-compression surface for the engine, the waverider design is used as the basis for the design of the entire vehicle, and the engine is generated within the pristine waverider definition while maintains the bow shock wave attaching to the leading edge. In this paper, the waverider applications by the domestic and overseas scholars in the airframe-inlet integration methodology for the air-breathing hypersonic vehicles are reviewed and classified. The idea for the design of a waverider-derived hypersonic vehicle can be summarized as follows:the modeling of the basic flow is used to design the waverider along the stream direction, and the osculating theory or the geometric design method is used to design the waverider along the spanwise direction. |
