航空发动机喘振主动控制技术的发展

摘要

概括了航空发动机喘振主动控制的三种控制策略的基本原理，分别为基于附加扰动喘振主动控制、基于分叉理论喘振主动控制及基于喘振预测主动防喘控制，总结了压缩系统稳定性模型、压缩系统失稳先兆及检测、主动控制传感器及执行机构等航空发动机喘振主动控制关键技术，及其存在的问题，并在此基础上预测了未来的发展趋势。%Surge active control, usual y adopted as an effective way to enlarge the compression system working field and to greatly enhance the aero-engine performance, is a focus issue on the research of gas turbine engine al long. Firstly, basic principles of three types of surge active control strategies were summarized:imposed disturbances based surge active control, bifurcation analysis based surge active control and surge active avoidance control. Secondly, key technologies of surge active control such as stability modeling, instability precursor detection, sensors and actuators for active control were given. At last, the development of surge active control method in the future was envisaged.
