摘要/Abstract

摘要： 根据涡轮发动机加减速控制规律设计的功率提取法原理,结合低转速部件特性预测方法,建立了用于双轴分排涡扇发动机起动控制规律研究设计的功率提取法模型,并编制了相应的计算程序。利用程序设计了某型双轴分排涡扇发动机单一状态和起动包线内的起动控制规律,并进行了相应的分析。计算结果表明,功率提取法能够应用于涡扇发动机起动控制规律的设计,并具有较高的计算精度。

Abstract: Power extraction method(PEM)of designing starting control law for turbofan engine was presented,and the computer program was developed.The PEM of designing starting control law is based on the principle of PEM of designing acceleration control law for turbofan engine,combined with the method of extrapolation of component maps.The starting control law for turbofan engine at single flight state and in whole starting envelope was designed by using the program.Computing results were analyzed.It shows that PEM is accurate and effective for designing starting control law for turbofan engine.
