摘      要：A new expansion cycle scheme of the scramjet engine system including a hydrocarbon-fuel-based(kerosene)regenerative cooling system and supercritical/cracking kerosene-based turbo-pump was proposed in this *** this cycle scbeme,the supercritical/cracking kerosene with high pressure and high temperature is formed through the cooling *** then,in order to make better use of the high energy of the supercritical/cracking fuel,the supercritical/cracking kerosene fuel was used to drive the turbo-pump to obtain a high pressure of the cold kerosene fuel at the entrance of the cooling *** the end,the supercritical/cracking kerosene from the turbine exit is injected into the scramjet *** supercritical/cracking kerosene fuel can decrease the fuel-air mixing length and increase the combustion efficiency,due to the gas state and low molecular weight of the cracking *** order to ignite the cold kerosene in the start-up stage,the ethylene-assisted ignition subsystem was *** the present paper,operating modes and characteristics of the expansion cycle system are first *** then,the overall design of the system and the characterisitics of the start-up process are analyzed numerically to investigate effects of the system parameters on the scramjet start-up *** results show that the expansion cycle system proposed in this paper can work well under typical *** research work in this paper can help to make a solid foundation for the research on the coupling characteristics between the dynamics and thermodynamics of the scramjet expansion cycle system.
