工作于M=0～7.5范围内的空天飞机进气道与一般的超音速进气道相比,有其特殊的要求。本文介绍了一种用于M=0～7.5的二元可变斜板进气道概念性设计方案,叙述了这种进气道的基本要求及在总压恢复、流量匹配、一体化设计等方面所必须考虑的问题,讨论了概念性设计的出发点、概念性设计方法及设计过程,其中着重讨论了设计点选择、各压缩角的确定等重要问题。作为一个算例,本文给出了一个二元可变斜板进气道的概念性设计结果,并作了简单的讨论
Air-to-air aircraft inlets operating from M = 0 to 7.5 have special requirements compared to typical supersonic air inlets. This paper presents a conceptual design of a dual variable swash plate inlet for M = 0 ~ 7.5, describes the basic requirements of this inlet and its application in total pressure recovery, flow rate matching, integrated design, etc. In this paper, the starting point, conceptual design method and design process of conceptual design are discussed. The important issues such as design point selection and determination of each compression angle are discussed. As an example, this paper gives a conceptual design of a dual variable swash plate inlet and gives a brief discussion
