A control system for operating a compressor bleed valve in a gas turbine engine to prevent compressor operation in surge region determines engine stability in response to a plurality of sensed engine parameters, and calculates and stores engine parameters to estimate compressor performance relative to a stability limit which is indicative of a surge operation. The control system further maintains a rolling average of the estimate of compressor performance for up to a predetermined number of engine flights. This rolling average of the estimate of compress...
[ What is claimed is:] [1.] A method for controlling the operation of a bleed valve in a compressor that is a part of a gas turbine engine, the method comprising the steps of:determining an engine stability condition in response to at least one sensed engine parameter;estimating, in response to the determined engine stability condition, compressor performance relative to a stability limit indicative of surge operation;maintaining, in response to the estimated compressor performance, a rolling average of the estimate of the compressor performance, wherein...
