摘要:

利用发动机通用起动模型 ,并对通用起动模型中低压转子影响效应的考虑方法进行了改进与完善 ,通过对某型涡扇发动机起动过程的模拟计算结果与试验数据的对比表明 ,改进后的起动模型能很好地揭示影响该类型发动机炮式起动成功的主要因素 ,其中一些影响因素是通用起动模型不能够考虑到的。改进模型对采用炮式起动的其他航空燃气轮机的起动过程研究有一定参考价值。

Abstract:

The cartridge starting characteristics of the two spool turbofan engine were researched by computer simulation. A mathematical model is developed from the generalized model by modifying the method of accounting for the effect of the low pressure spool. Compared with the testing data, the simulation results can easily evaluate the main factors that affect the starting characteristics. The developed mathematical model is also useful for studying the starting characteristics of other types of gas turbine engines with cartridge starters.
