| Research Abstract |
Detonation is the combustion mode of most intense explosions. The pulse-detonation technology is a technology where detonations are repetitively initiated in a tube, one end of which is closed and the other end open, and hot gas jets are continually created. In order to apply this technology to the field of gas-turbine engines, we carried out experimental studies on the applications of pulse-detonation combustors as the combustors of gas-turbine engines and as the heat sources of the thermal spray. On the former, we constructed a pulse-detonation-turbine-engine system, realized the thermal efficiency of approximately 10%, and clarified the energy balance of the system. On the latter, we constructed a pulse-detonation-thermal-spray system, measured the temperature and speed of alloy powders, which were heated and accelerated by pulsed detonations, and showed that we successfully made a coating, which satisfied the requirements for turbine blades, with proper thermal-spray conditions.
