Abstract:
Based on the MSC.EASY5 platform, the simulation models of main components in the operation process of liquid rocket engine were developed to improve the analysis ability in the steps of project design and system performance estimation. By linking the Fortran or C code with EASY5, the component models and fluid types were extended further to make them applied to the study of liquid rocket engine. The system model of the liquid rocket engine were established according to the circulation way of the engine. The system model of RD-170 engine was built and simulating calculation of steady-state points was conducted to validate the correctness of the models. The simulation result coincides with the available materials. The simulation accuracy is high. The results show that the modeling and design and performance estimation of liquid rocket engine with continuous efforts of improving the models.
