Abstract

A turbine engine accessory power unit has a compressor bleed air control system in which a surge bleed valve is proportionally and integrally controlled to maintain a constant minimum compressor bleed flow rate slightly above the compressor's surge flow rate. The system control parameter is automatically reset as a function of the position of the compressor's adjustable inlet guide vanes to assure optimum control system performance throughout the air delivery range of the compressor.
