The article describes the structure of a step brake device in the flow control for pulsed thrusters. The device provides a smooth control of the thruster throat section as a function of the operational temperature conditions. The authors performed a threedimensional numerical simulation of penetration of the flow control valve elements into a damping barrier. The article shows that the pressure of the thruster with a flow control valve can be stabilized by means of the controlled dissipation of the opening kinetic energy driven by the propellant gases at a given distance.
