总结了近十年来弯曲激波压缩研究的主要成果。提出了弯曲激波压缩系统的新概念,即利用特殊设计的楔形弯曲压缩面或空间弯曲压缩面,产生一系列与前缘弱激波相互交汇或叠加的压缩波系,从而使前缘激波弯曲,形成特殊的弯曲激波,它与波后的等熵压缩波来共同完成对气流的压缩。在此基础上,实现了由给定出口气动参数的超声速内流道反设计,实现了由给定压缩面压力分布和给定压缩面马赫数分布要求的型面反设计,实现了由给定激波波面的压缩型面反设计。研究证明,弯曲压缩面-弯曲激波压缩系统具有良好的综合气动性能,为高性能高超声速进气系统的气动设计提供了一种全新的设计方法。
The main achievements of the research on bending shock compression in recent ten years are summarized. A new concept of bending shock compression system is proposed, that is, using a specially designed wedge-shaped compression surface or a space-bending compression surface, a series of compressional wave systems intersecting with or superimposing weak shocks on the leading edge are generated, Bending, the formation of a special bending shock wave, it and wave after the isentropic compression wave to complete the compression of the airflow. On this basis, the supersonic inverse flow design of a given outlet is achieved, and the inverse design of the profile of a given compression surface and the Mach number distribution of a given compression surface is achieved. Shock Wave Compression Surface Reverse Design. The research shows that the bending compression surface - bending shock compression system has a good overall aerodynamic performance, which provides a new design method for the aerodynamic design of high performance hypersonic intake system.
