Investigation of properties of system of automatic control of liquid-propellant rocket propulsion system with integrating regulator

Abstract

There are considered the dynamic properties of the system of automatic control of the unitary fuel supply to a singlecomponent gas generator of a liquid rocket engine. There are obtained differential equations describing the operation
of the comparison element, the throttle valve, the hydraulic amplifier, and the processes in the gas generator. The final equation of the mathematical model of the system operation is proposed, which allows to reveal the main regularities of the influence on the static error and the static accuracy of the external action and the command value. The results presented in this paper make it possible to obtain static and dynamic properties of the elements of the automatic control system based on the controller with integrating properties.
