摘要: 通过在一台实验用对旋风机上的大量性能实验,比较分析了对旋风扇在不同转速比匹配和不同轴向间隙条件下的特性曲线和失速边界的变化,并通过用球头五孔压力探针对其级间稳态流场的测量,对对旋风扇在不同转速比和轴向间隙下的流场特点作了进一步的分析.最后,在总结实验分析结果和国外类似研究的基础上,对对旋轴流压缩系统的增压、扩稳途径提出了一些新的观点.

Abstract: Through experiments on a contra-rotating fan, the performance base line and stall margin have been analyzed at varies rotate speed matching and varies axial gap between two rotors. Used global five-hole pressure probe, the steadyflow field between contra-rotating rotors has been also measured, and the especial aerodynamic characteristic of contra-rotating fan has been analyzed more deeply when its rotate speed and axial gap changed. At last, basing on the experiment results and the same research in the world, this paper conclude some viewpoints on the means of raising pressure and stable range of a contra-rotating axial compressor system.
