Abstract:
An anti-rotation lock (61) for preventing circumferential movement of a stator segment (30) in relation to a split case (32) to which it is mounted is disclosed. A racetrack shaped pocket (62), disposed within the case (32) and proximate the stator segment (30), is suitably sized to receive a lug (64) and a spring pin (66). The lug (64) is received in the pocket (62) and protrudes radially inward from the case (32) and is engagable by the stator segment (30), thus preventing circumferential movement with respect to the case (34). The spring pin (66) is received adjacent to the lug (64) and compressively retains the lug (64) in the pocket (62).

Abstract:
A variable vane includes a variable vane body that has an airfoil portion. The variable vane body is formed of a first material. A trunnion is attached at one end of the variable vane body. The trunnion includes a pivot formed of a second, different material.
Abstract:
An assembly for use in a gas turbine engine includes an inner diameter (ID) shroud having a plurality of ID slots and an outer diameter (OD) shroud having a plurality of OD slots and positioned radially outward from the ID shroud. A plurality of stator airfoils extend from the ID shroud to the OD shroud. Each of the stator airfoils is positioned at least partially in one of the ID slots and is positioned at least partially in one of the OD slots. A bumper is positioned proximate a first end of each of the stator airfoils so as to limit movement of the stator airfoils in a radial direction.
