Performance optimization of hypersonic inlets with pulse periodic energy addition

To optimize the law of pulse periodic energy addition and to obtain maximum performance improvement of hypersonic inlets, the performance analysis of hypersonic inlets with pulse periodic energy addition is investigated. First, the unsteady numerical simulation of hypersonic inlets with different pulse periodic energy additions was performed, and then the effect of the duty cycle and pulse frequency of the energy addition on the performance parameters of hypersonic inlets was discussed. The simulation result shows that the averaged performance parameters of hypersonic inlets are improved by increasing the duty cycle or the pulse frequency for the same averaged energy addition rate. These can provide some beneficial references for optimization of the law of pulse periodic energy addition to obtain maximum performance improvement of hypersonic inlets.
