The investigation shows the performance gets quite insensitive to the prewhirl angle of IGV as the stagger angle of diffuser vane is reduced to the minimum 7 °;
研究表明:扩压器进口安装角最小值为7°时,压缩机性能对进口导叶预旋角不敏感;
A optimal diffuser stagger angle should exist at a fixed mass flow rate to make the diffuser have highest efficiency;
在给定的流量工况下,应存在一个最佳的进口安装角,使得扩压器效率最高;
The algorithm selects baseline length satisfied stagger qualification, thereby solving conflict between accuracy of direction finding and maximum unambiguity angle.
该方法选择基线长度满足一定的参差关系,从而解决了测向精度与最大不模糊角度之间的矛盾。
