Abstract: Anti-rotation knife edge seals and gas turbine engines including the same are provided. The anti-rotation knife-edge seal includes a first end portion having at least one knife edge, an opposing second end portion including an outside peripheral edge having a nut anti-rotation feature and an inside peripheral edge having a shaft anti-rotation feature, and an intermediate portion extending between the first end portion and the opposing second end portion. The first end portion, the opposing second end portion, and the intermediate portion form a one-piece annular seal member. A method is also provided for substantially preventing rotation of a stack nut against an adjacent rotatable component.

Abstract: A seal assembly for a bearing compartment includes a coupler with a lip, seal plate, nut, and air seal land. The seal plate is disposed on and around the coupler and is in contact with the lip. The nut is disposed within the bearing compartment and adjoining the seal plate. The nut includes first, second, and third major portions and first and second intermediate portions. Each of the first, second, and third major portions is in the shape of an annular band. The second major portion is disposed axially between the first and third major portions. The third major portion includes a knife edge seal extending radially outward. The first and second intermediate portions include frustums and extend between the first and second major portions and second and third major portions, respectively. The air seal land is sealingly engaged with the third major portion of the nut.

Abstract: A squeeze film damper bearing assembly includes a bearing and a squirrel cage radially outward of and supporting the bearing. The squirrel cage includes a first piston ring groove, a second piston ring groove, and a first pocket connected to the first piston ring groove. The squeeze film damper bearing assembly also includes a first piston ring configured to fit into the first piston ring groove. The first piston ring includes a first end circumferentially spaced apart from a second end and an ear configured to fit into the first pocket to prevent the first piston ring from rotating in the first piston ring groove. The squeeze film damper bearing assembly also includes a second piston ring configured to fit into the second piston ring groove and a stationary housing radially outward of the squirrel cage.
