Abstract
In order to study the effect of variation of angle of attack on restart behavior of the supersonic inlet, the unsteady restarting process of the supersonic inlet response to variation of angle of attack was simulated with two-dimensional unsteady compressible N-S equations and SSTk-ω turbulence model. The results show that the supersonic inlet at unstart can achieve restart by changing the angle of attack properly, and the value of the restart angle of attack tends to increase linearly with the change rate of the angle of attack, and performance differences of the supersonic inlet between steady and unsteady cases at the same angle of attack are more apparent at a high change rate of the angle of attack.关键词
