Abstract:
In order to obtain the influence of different fuel on engine performance,based on the components and engine experimental data,an engine characteristic analysis model was established,which adopt the control body method and taked into account the effects of heat complete gas,chemical equilibrium flow,viscosity loss and heat loss. Model engine was used to complete the simulation with kerosene,methane,and hydrogen. The effects of different fuel types on the engine force and specific impulse under given ballistic were obtained as the same time. The results show that:H2 achieved maximum performance,the engine force on ejector mode,rocket ramjet mode,and ramjet mode is 1.40,1.28,1.14 times to kerosene respectively,and 1.40,1.43,2.73 times respectively for engine specific impulse methane and kerosene had similar properties,the engine force on ejector mode,rocket ramjet mode,and ramjet mode is 1.08,1.04,0.97 times as much as kerosene respectively,and 1.08,1.08,1.17 times respectively for engine specific impulse.
