摘　　要：本文采用等平均速度流动方法对轴流压气机试验台用径向排气蜗壳进行设计,主要研究了蜗壳截面形状、蜗壳轮廓线不同渐开方法、蜗壳0°相位截面面积取值对排气系统周向反压不均匀度的影响。同时,提出了一种在蜗壳0°相位截面增设隔板,抑制排气系统进气旋流角对排气系统周向反压不均匀度影响的方法。In this paper,the radial exhaust volute applied in axial compressor test rig was designed by using the method of constant average velocity.The influence of the volute section shape,various in volute design approaches for the volute contour,and the size of the volute 0°phase section area on the exhaust system’s circumferential backpressure non-uniformity were investigated.At the same time,a method is proposed to add a baffle at the 0°phase section of the volute to suppress the influence of the intake swirl angle of the exhaust system on the circumferential backpressure non-uniformity of the exhaust system.
