【Abstract】 To meet the requirement of a combustor in a ground surface test facility for a high temperature rise,designed was an evaporation type combustor with a temperature rise of 1 350 K.According to the overall structure of the combustor,its main components were designed.Through the aerodynamic and thermodynamic calculation of the combustor,the overall dimensions of the combustor and the opening hole dimensions of the flame tube were determined.On this basis,a performance test of the combustor was conducted to a certain extent.The test and application results show that the combustor thus designed features a safe and reliable operation,a simple structure,as well as a high space utilization rate,a quick temperature rise speed and a clean exhaust gas.In the whole operation range,the combustion efficiency can reach 0.95~0.97 and the non-uniformity of the temperature field at the outlet is lower than 0.09,thus meeting the design requirements.更多还原
