Abstract

This paper presents a liquid propellant rocket engine (LPRE) model library in Modelica language, containing component models such as pipes, valves, tanks, turbo-pumps, combustion chambers, nozzles, injectors, gas generators, etc. These component models can be applied to establish a variety of liquid rocket engine systems with the capability of predicting engine transient performance during startup process, shutdown process and regulation process. Typical gas-pressurized liquid propellant engine system and turbo-pump liquid propellant engine system are modeled in the paper. Some simulations and analysis are performed to validate models qualitatively. All work is implemented in MWorks, which is a modeling and simulation platform full supporting Modelica.
