| Abstract: | The combustion efficiency was a critical parameter for scramjet combustor performance evaluation.But restricted by the high speed and temperature of the complex combustor internal flow,it was very difficult to gain the combustion efficiencies directly.The most frequently used methods of gaining the scramjet combustion efficiency,such as,gas sampling method,infrared measurement method,bulk calorimeter method,force based measurement and impulse function method etc.,were clearly introduced and curtly compared,which can provide instructions and references for related field researchers. |
