摘　　要：目前国内外提高亚音速S弯进气道气动特性的方法大部分是改变进气道的几何形状,而通过流动控制技术来改善进气道流场结构方法较少。本文以某高亚音速无人靶机集成涡喷发动机进气道为研究对象,通过流动控制技术方法设计了有吸除缝的半埋入式S弯进气道,采用CFD仿真方法对有无吸除缝的半埋入式S弯进气道进行了比较分析,结果表明,带吸除缝设计S弯进气道的总压恢复和流场畸变等性能均得到较大提高。At present,most of the methods to improve the aerodynamic characteristics of subsonic s-shaped intake at home and abroad are to change the geometry of the intake,while there are few ways to improve the flow field structure of the intake through flow control technology.This paper takes the intake of an integrated turbojet of a hypersonic drone as the research subject,and the semi-buried s-shaped intake with suction and removal seam is designed by flow control technology method.CFD simulation method is used to conduct a comparative analysis between the semi-buried s-shaped intake with suction and removal seam and the one without it,and the results show that the total pressure recovery and flow field distortion of the s-shaped intake with suction and removal seam are greatly improved.
