摘要

以一台单级低速轴流压气机为研究对象

采用在压气机周向、轴向不同位置处布置多个动态压力传感器的方法

获取了压气机失速过程中不同位置动态压力信号的变化情况

通过对各测点的压力信号分别进行了时域、频域分析.结果表明:压气机在失速前出现尖脉冲型扰动;失速后的失速团的有分裂和合并的现象

个数在1和2之间相互转换

但退出失速时总是由两个合并成为一个

并且在几个转子周期内迅速退出;对失速时的压力信号频谱分析证明了对失速团个数判断的准确性.

Abstract

The stall inception of a single low speed compressor was investigated with uniform inlet flow.By installing high response dynamic pressure transducers in the circumferential and axial directions

the dynamic pressure data at different positions were collected and analyzed using time analysis and frequency analysis

respectively.The results indicate that the spike-type inception will appear before stall;the stall cells are splited and incorporated

but two cells are always incorporated to one when exiting from stalling quickly;and frequency analysis of the dynamic pressure validate the veracity of the number of stall cell.
