Modeling and Performance Simulation for Gas Generator of Aeroengine Based on Modelica and Dymola

基于对压气机、涡轮与燃烧室共同工作条件的分析,建立了1种快速简便的单轴燃气发生器性能仿真模型;用Modelica语言和Dymola编译器实现了单轴燃气发生器的性能仿真,验证了该模型的有效性。结果表明:该模型能够模拟单轴燃气发生器的性能,并能实现非设计转速小流量工况下的性能仿真。

A rapid, simple and convenient performance simulation model for single spool gas generator of aeroengine is created based on analysis of the co - operation conditions of compressor, combustor and turbine. The performance simulation for single spool gas generator is comp｜eted using computer language Idodelica and the editor Dymola. The validity of the model is verified. It is shown that the model can properly simulate the performance of single - spool gas generator even in the states of off- design rotating speed and small flux.
