Abstract: A fixed geometric,dual mode supersonic combustor was selected and the thermodynamic adjustment method,which means the adjustment of the way of fuel injection and heat release rate of combustion,was adopted to realize dual mode combustion with a wide range Mach number.One dimensional constant specific heat model was taken to analyze the influence of the related parameters on the combustion mode transition and the combustor performance.The interaction between the isolator and the combustor was also analyzed.The results demonstrate that the thermodynamic adjustment method is viable to be adopted to realize the combustion mode transition in a supersonic combustor.
