Abstract
A method of diaphragm rupture controlled by igniter to simulate inlet unstart/restart process is used to investigate the self-starting characteristics in shock tunnel. Based on Van Wie’s inlet models, various experiments have been conducted to investigate the effects of cowl shock wave strength on the inlet self-starting performance. Results show that the cowl shock wave strength dominates the inlet self-starting capability, and the inlet self-starting internal contraction ratio (ICR) decreases rapidly with a relatively strong cowl shock wave in a certain range. Based on the results, noncoalesced shock design was taken to reduce the cowl shock strength, and the ICR of inlets increased significantly.
