Mathematical description of the processes in the pumping system for supplying fuel to the combustion chamber of a liquid rocket engine

Abstract

The article considers a mathematical model of a pumping system for supplying fuel to a liquid rocket engine chamber consisting of active and passive parts of a hydraulic system. A differential equation describing the processes occurring in the fuel supply system is obtained. The mathematical model makes it possible to analyze and identify the main patterns of influence of the control and disturbing quantities on the controlled quantity, as well as to obtain transients.
