Abstract: A new type of output flow stabilized regulator used in high pressure staged combustion liquid propellant rocket engines is introduced.And on the basis of theoretical modeling,the characteristics of the step response and amplitude frequency response of the flow regulator were investigated by means of computer simulation.The effect of damping coefficient was also investigated
