| Abstract: | 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. |

| Keywords: | inlet starting test cowl lip open process internal contraction ratio experimental investigation |
