ABSTRACT	The effects and limitations of regenerative cooling on rocket engine specific impulse was investigated with a quasi one-dimensional simulation model.Regenerative cooling of a rocket engine nozzle skirt was shown to increase engine specific impulse,and such increase being explained in two ways:net entropy depression in the engine,and acceleration of the supersonic heated gas by cooling.When the Reynolds number of the combustion gas was small,the regenerative cooling effect on specific impulse became relatively large.
