【摘要】 对近期有应用前景的碳氢燃料（煤油）超燃冲压发动机性能进行了计算。探讨了固定几何尺寸（不可调）的超燃冲压发动机有效推力系数、有效比冲和有效单位推力等主要性能参数变化的定量范围。计算表明，几何尺寸不可调的煤油超燃冲压发动机将可能成为巡航马赫数６左右的导弹动力装置。更多还原

【Abstract】 The performance of hydrocarbon fueled scramjet which is promising recently is analysed.The main performance parameters of a fixed geometry scramjet are observed,and the effective thrust coefficient,effective specific impulse and effective specific thrust are determined.The results show that the kerosene(JP) fueled scramjet of fixed geometry could be adopted as a propulsion engine for the cruise vehicle of the flight Mach number about 6更多还原
