Abstract

Abstract

The main difficulty in aeroengine startup procedure lies in lack of component characteristics at low speed.In order to solve this problem,a method of acquiring compressor's low speed characteristics based on parabola extrapolation was studied.According to the examples for compressors of two different types of engines and the reasonable criterion,this method is characterized by exactness and universality.
