BLEED VALVE ASSEMBLY FOR A GAS TURBINE ENGINE

A gas turbine engine includes a casing surrounding the first compressor, and a liner extending forward from the first compressor. The gas turbine engine also includes a bleed air assembly. The bleed air assembly includes bleed valves positioned in the liner and spaced in the circumferential direction of the gas turbine engine. The bleed air assembly also includes pipelines in air flow connection with the bleed valves and defining outlets in the housing. During operation, the pipelines discharge air from the bleed valves to the outlets. 种燃气涡轮发动机包括围绕第压缩机的壳体以及从所述第压缩机向前延伸的衬垫。另外，所述燃气涡轮发动机包括放气组件，所述放气组件具有定位在所述衬垫中且沿所述燃气涡轮发动机的圆周方向间隔开的多个排放阀。所述放气组件还包括与所述多个排放阀成空气流动连通且在所述壳体处限定出口的管道。在操作期间，所述管道将流动放气从所述多个排放阀提供到所述出口。
