Compressor Characteristic Map Calculation Based on Coordinate Method

压气机特性数据是通过大量实验而获取的,结合发动机调节规律对压气机特性数据进行计算,可获得整台发动机的特性,从而缩短发动机研制周期。该文根据某研制中的压气机特性数据,使用坐标数值方法对航空发动机特性进行了计算研究,且基于VB语言开发了相关的程序,实现了高压压气机和低压压气机共同工作线的计算、绘制以及发动机的特性的计算。

Compressor characteristic data is acquired through a lot of experiments.The aeroengine characteristics can be gained by calculating the compressor performance data under the engine control law.Based on some compressor performance characteristics data, a study of the coordinate method for aeroengine computational simulation is reported.Under the condition of given mode of control, the operating curves of the high-pressure and low--pressure compressor are computed and drawn by means of VB,also the engine performance is analyzed in this paper.
