  • COMPRESSOR BLEED
    Publication number: 20040191058
    Abstract: A turbine engine stator segment has an outer wall segment with inboard and outboard surfaces. An inner wall segment has inboard and outboard surfaces essentially sharing an axis with those of the outer wall segment. Airfoils forming a sector of a first airfoil stage extend between the wall segments. The outboard wall segment has a compressor bleed port mounted at least along a forward edge by a lip projecting rearward and radially outward. The lip has inner and outer surfaces and a rim and projects radially beyond an adjacent portion of the outer wall segment.
