| Research Abstract |
In the present study, we proposed the detonation engine mechanism (detonation resonatormechanisms and the curved-channel detonation engines), and we confirmed and analyzed these mechanisms by experiments and CFD analysis. Regarding the detonation resonator mechanism, we obtained frequency-independent stable operation of the engine using a rotary valve. We also successfully visualized all of the flow fields in the pulse detonation engine cycle at 160-Hz operation. The Deflagration-to-Detonation Transition phenomena near the closed wall of the tube-shaped engine were analyzed. The maximum specific impulse and thrust of the engine was 232 sec and 71 N, respectively. By the visualization of the curved detonation wave propagating in the curved channel, we determined the stable operation condition for the curved-channel detonation engines. We also developed the Multi-frame Short-time Open-shutter Photography Method (MSOP Method), by which we simultaneously observed both the wave shape of the curved detonation wave and cell sizes of the waves.
