    Abstract: A variable-pitch vane assembly for a gas turbine engine includes a sync ring, a vane having a vane arm, and a pin installed through the sync ring and through the vane arm. The pin includes an anti-rotation notch located along a pin shaft. An anti-rotation spacer is engaged with the pin at the anti-rotation notch to prevent rotation of the pin. A turbine section of a gas turbine engine includes a turbine rotor and a turbine stator. The turbine stator includes one or more variable-pitch vane assemblies including a sync ring, a vane having a vane arm, and a pin installed through the sync ring and through the vane arm. The pin includes an anti-rotation notch located along a pin shaft. An anti-rotation spacer is engaged with the pin at the anti-rotation notch to prevent rotation of the pin.

    Abstract: An assembly for a turbine engine includes a plurality of vane segments. The vane segments are fastened together and form an adjustable stator vane that pivots about a variable vane axis. The adjustable stator vane includes a stator vane body, a shaft and a flange. The stator vane body extends axially between a first end and a second end, and includes an airfoil, a body surface and a cavity. The body surface is located at the first end. The cavity extends axially from an inlet in the body surface and into the airfoil. The shaft extends along the variable vane axis from the first end. The flange extends circumferentially at least partially around the inlet, and radially from the stator vane body. A first of the vane segments includes the flange. A second of the vane segments includes at least a portion of the airfoil.

    Abstract: A vane support system includes a frame and a vane. The frame has a first end configured to engage to a first platform and a second end configured to engage a second platform, so the frame can structurally support at least one of the first platform and the second platform. The first and second ends define a vane axis therebetween. The vane is mounted to the frame about the vane axis. A gas turbine engine includes a case defining a centerline axis of the engine, an inner housing and a plurality of variable vanes. The inner housing is radially inward of the case with respect to the centerline axis. At least one of the variable vanes structurally supports the case and the inner housing in response to at least one of radial, axial or tangential loads with respect to the centerline axis.

    Abstract translation: 叶片支撑系统包括框架和叶片。 框架具有构造成接合到第一平台的第一端和被配置为接合第二平台的第二端，因此框架可在结构上支撑第一平台和第二平台中的至少一个。 第一和第二端限定其间的叶片轴线。 叶片围绕叶片轴线安装到框架上。 燃气涡轮发动机包括限定发动机的中心轴线的壳体，内壳体和多个可变叶片。 内壳体相对于中心线轴线在壳体的径向内侧。 响应于相对于中心线轴线的径向，轴向或切向负载中的至少一个，可变叶片中的至少一个结构地支撑壳体和内壳体。
