摘要/Abstract

摘要： 针对目前对超燃冲压发动机阻力特性的需要,以侧压式进气道为例,分别以内壁面和捕获流管为分析体,对其内部阻力进行分类;以数值模拟为手段,给出了总阻力的大小及各项阻力的分配比例,并分析了进气道几何参数变化对阻力的影响关系。

Abstract: The classification of the internal drags on sidewall-compression inlets was presented for the requirement of drag characters on scramjet.The walls inside of the inlet and captured flow tubes were used respectively to analyze drags.The total drag and component of different internal drag were given through numerical investigation.The influence of inlet configurations to the internal drag was discussed.

Key words: Sidewall-compression inlet;Friction drag;Pressure drag;Additive drag;Drag distribution
