BASIC STUDIES OF ROTATING STALL AND AN INVESTIGATION OF FLOW-INSTABILITY SENSING DEVICES. PART II. INVESTIGATION OF FLOW INSTABILITY SENSING DEVICES.

Abstract

The report describes the results of an experimental investigation of pure fluid flow-instability sensing devices that might be applied to the detection of incipient stall in jet-engine compressors. Various sensors employing two-branch probes and bistable fluid amplifiers were investigated. The results of dynamic tests, including operation at high temperatures, are described. The preferred configuration evolved exhibits good performance characteristics and offers a promising solution to pure fluid flow-instability sensing problems. (Author)
