本文介绍了现代跨音速高速单级轴流风扇试验台在喘振和旋转失速过程中的一套独特的非定常压力测量。非定常压力数据是使用位于转子尖端的22个高频响应Kulite传感器阵列采集的，以显示失速和喘振期间通道内流动行为的详细信息。此外，Kulites还位于钻井平台的上游、下游和旁路管道中，以更全面地了解旋转失速和喘振事件期间的风扇运行情况。
This paper presents a unique set of unsteady pressure measurements during a surge and rotating stall event in a modern transonic high speed single stage axial flow fan rig. The unsteady pressure data were acquired using an array of 22 high frequency response Kulite transducers positioned over the rotor tip to show detail of the in-passage flow behaviour during stall and surge. In addition, Kulites were also positioned upstream, downstream and in the bypass duct of the rig to give a more general overview of the fan operation during the rotating stall and surge events.
