摘要: 针对在建立起动过程数学模型时发动机部件低转速特性难以获取的问题,提出了基于抛物线外推的压气机低转速特性获取方法.给出了两种型号发动机的压气机外推实例,结合发动机部件低转速特性外推的合理性判据可知,所提方法具有较好的准确性和通用性.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.
