| Abstract: | In order to investigate the effect of different intensifying combustion setting on detonation initiation of kerosene/air mixture, and to choose optimal intensifying combustion setting for kerosene/air aero-valve pulse detonation engine, several kinds of intensifying combustion setting were designed and tested. Much detonation experimentation was carried out and the kerosene/air aero-valve PDE could be operated at different frequency. The mechanism of intensifying combustion setting was analyzed, and the effect of different intensifying combustion setting on detonation initiation of kerosene/air mixture was described. This investigation is of importance to supply theory and practice for optimizing intensifying combustion setting and kerosene/air aero-valve pulse detonation engine. |
