Abstract
The theory of pulse periodic energy addition to hypersonic airflow off a vehicle to increase air mass capture and improve the performance of hypersonic inlets at Mach numbers below the design value is explored. The unsteady numerical simulation of hypersonic inlets with energy addition was performed, and pulse periodic energy addition was introduced to discuss the possibility of the steady performance improvement of hypersonic inlets. The numerical simulation of hypersonic inlets at different pulse periodic energy addition rates was carried out. The simulation result shows that the performance parameters are improved at pulse periodic than at fixed values for the same averaged energy addition, and the energy addition rate needed is less at pulse periodic than at fixed values for the same performance parameters of hypersonic inlets.
