摘要： A turbine engine accessory power unit has a compressor (18) provided with a bleed air control system in which a surge bleed valve (58) 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 (inter- alia) the position of the compressor's adjustable inlet guide vanes to ensure optimum control system performance throughout the air delivery range of the compressor.
