In order to research the influence on the overall performance of scramjet with Pre-jet (jetting fuel or water vapor into the isolator) fuel, the governing equations of the different component in scramjet and the ideal performance analysis model with Pre-jet fuel are established. Moreover, Pre-jet fuel is considered based on the ideal Brayton cycle. The results of ideal performance analysis show that Pre-jet fuel doesn’t burn at a given maximum temperature of the combustor exit. Due to the increasing of oil to air ratio with Pre-jet fuel, the outlet temperature of the isolator drops more. However, fuel potential of the combustion, the flux of working fluid and the engine thrust ratio are increased. Meanwhile, the influence of methane and water vapor on the engine performance is similar, because the Pre-jet fuel is small and there are some similarities between methane and water vapor.
