摘要

摘要: 针对一台跨声速压气机转子在不同转速下的失速过程进行了稳态和动态实验研究.通过对原始信号、小波分析结果以及FFT(fast Fourier transform)变换结果的分析得到,该压气机转子在3个不同转速时均为突跃型全叶高失速,流场中存在一个失速团,失速团沿周向的传播方向与转子转动方向相同,其相对静止坐标系的量纲一转速随转子转速的增大而减小,对这一规律产生的原因进行了分析.

Abstract: An experiment with static and dynamic acquisition were carried out on a transonic compressor rotor at three rotating speed.The analysis was performed on the original signal,the FFT(fast Fourier transform)and the wavelet method.The results show that the stall inception is spike type of whole span.Only one stall cell exists in the flow field,the spreading direction of which is the same as the rotor rotating.And the relative rotating speed of the stall cell decreases when the rotor speed increases.
