Abstract: An example variable stator vane assembly includes at least one button, a vane airfoil adjacent to the button, and a fillet defined between the button and the airfoil. In one example, the fillet defines a constant radius and extends beyond the button at least greater than a distance of 60% of a length of an overhang portion of the vane airfoil.

Abstract: An adapter to permit borescope access inside a gas turbine engine including a compressor stator having a plurality of compressor stator segments comprises a body portion defining a bore extending longitudinally therethrough from a first end to be disposed adjacent to outside surfaces of adjacent compressor stator segments to a second end to be disposed adjacent to inside surfaces of adjacent compressor stator segments. The bore permits a borescope to enter therethrough. The adapter further comprises an attachment portion for circumferentially coupling at least one compressor stator segment to an outer casing of the gas turbine engine.

Abstract: A damper for a stator assembly, the stator assembly comprising a stator segment and a seal mounted to the stator segment. The damper locates between the stator segment and the seal, and comprises: a medial section; and opposed arms extending from the medial section. The medial section engages one of the stator segment and the seal and the opposed arms engage the other of the stator segment and the seal. A method of making the damper, comprising the steps of: providing a sheet of material having a medial section and opposed arms extending from the medial section; forming a bend at the medial section so that the medial section can engage one of the stator segment and the seal; and forming a bend at each of the arms so that the arms can engage the other of the stator segment and the seal.

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.
