通过数值计算，得到了喷嘴出口自由射流与冲击射流情况下的流体速度、压力等参数分布情况，及这两种流场中的激波位置。

Through the numerical simulation, the distribution of those parameters such as speed, pressure of the free jet and impinging jet flow is obtained, also the position of shocks.

实验中，自主设计了高超声速直联式风洞模拟自由来流马赫数5.3，通过测量进气道上壁面压力分布，研究了进气道开启过程的起动特性；

During experiment, a directly connected wind tunnel was independently designed to simulate a free stream Mach at 5.3, based on which the dynamic process of inlet opening was studied;
