High temperature and high pressure condition was achieved at the implosion center by using imploding detonation. Flame jet obtained from the implosion center ignites Methane-oxygen enriched air mixture filled in the main combustion chamber. Initial pressure was changed from 0.3 MPa to 0.6 MPa. The experimental results show that the maximum pressure at the implosion center was 300 to 400 times higher than the initial pressure, which was due to imploding detonation obtained in the initial pressure of more than 0.4 MPa. Flame jet by imploding detonation significantly reduced the burning time in the main combustion chamber to 1/60〜1/100 in the case of no transition of detonation.
