宽速域乘波构型设计方法研究综述

乘波体是一种典型的高速气动构型,由于高升阻比和均匀的下表面流动等特性使其成为机身/进气道一体化设计的理想构型。随着对乘波体设计方法的不断研究,提高乘波体在非设计条件下的气动性能,实现乘波体的宽速域飞行成为乘波体实用化的一个重要研究方向。将目前的宽速域乘波体设计方法分成变马赫数、多级组合和涡波结合3种类型,并详细介绍了这些方法的设计过程,分析了设计方法的优缺点。

Review on the Design Methodology of Waverider for a Wide-Speed Range

The waverider is a typical high velocity aerodynamic configuration. Due to its high lift-drag ratio and uniform lower surface flow characteristics, it has become an ideal configuration for the integrated fuselage / intake design. With the continuous research on the design method of the waverider, improving the aerodynamic performance of the waverider under non-design conditions, and realizing the wide-speed flight of the waverider have become an important research direction of the waverider practicality. This paper divides the current design methods of wide-speed waverider into three types: variable Mach number, multi-stage combination and combination of shock and vortex. The design process of these methods is introduced in detail, and the advantages and disadvantages of these design methods are analyzed.
