摘要
设计了小型直联式实验台,模拟来流马赫数5.3,对一组具有不同内收缩比的二维进气道唇口开启过程及其特性开展了实验研究。进气道唇口的角度位置和隔离段高度均可调节,由此实现进气道不同内收缩比要求。通过分析进气道底板壁面压力分布,总结了进气道开启过程特性及其影响因素。
An experimental direct-connected facility was designed to simulate the flow with Mach 5.3. This can be used for experimental investigation on the cowl lip＇ s open process of two-dimensional inlet. In order to achieve different internal contraction ratio of inlet, the angle position of cowl lip and the height of isolator were designed to be changable. By analyzing the pressure distribution on the inlet＇ s bottom wall, the characteristic of inlet＇s open process and the influence factors were summarized.
