Unstart/restart is one of most important phenomenon in hypersonic inlets
which affects the operation range and the restart capacity.Atwo-dimensional internal flow field of mixed-compression hypersonic inlets was simulated numerically.The flow characteristics of unstart/restart caused by variations of attack angle were also investigated.The reasons behind the formation of inlet unstart/restart was discussed from the viewpoint of hydrodynamic stability.The inlet performance parameters varying with angle of attack were analyzed.Finally
