초록

The method controls gas flow in an axial flow compressor in which the flow at one or more chosen station in the direction of flow through the compressor is sensed at a series of circumferentially spaced positions. Flow variations above a predetermined limit are evaluated to initiate a response if a disturbance above a predetermined acceptable level is detected. When such a disturbance is detected, higher pressure gas bled from downstream is injected at a station to supplement the main gas flow. An incipient rotating stall cell will appear as a variation ...

A method of controlling gas flow in a compressor comprising the steps of sensing the flow at a series of circumferentially spaced positions at a chosen axial station in a direction of flow through the compressor to detect variations in the flow above a predetermined limit of variation and, upon at least one of the variations being detected, injecting higher-pressure gas from a region downstream of said chosen station into the flow through the compressor upstream of said region generally in said direction of flow and in a circumferentially selective manne...
