Abstract: An example case for a gas turbine engine includes a bearing compartment, a radially outer ring, and a radially inner ring. The radially outer ring and radially inner ring are connected by a plurality of circumferentially spaced apart struts and define an annular flow path therebetween. The radially inner ring includes a first flange that extends radially outward from the bearing compartment. The first flange includes an undulation that extends axially away from the plurality of struts, and defines a load path between the bearing compartment and the radially outer ring.

Abstract: A component for a gas turbine engine includes at least one airfoil that has a radially inner end and a radially outer end. A platform includes a radially outer surface that is attached to the radially inner end of the airfoil. A radially inner side of the platform includes a forward surface and an aft surface. A pocket is recessed into at least one of the forward surface and the aft surface. A cover plate covers the pocket and a seal is attached to the cover plate.

Abstract: Aspects of the disclosure are directed to a brush seal assembly, comprising a compressible core, at least one wire wound around the core, and a backing plate that is substantially ‘c’ shaped or ‘u’ shaped that at least partially encases the at least one wire. Aspects of the disclosure are directed to a method comprising separating compressible cores with a spacer, winding wires around the cores and the spacer, and forming substantially ‘c’ shaped or ‘u’ shaped backings about the wires to obtain a package of brush seal assemblies.

Abstract: A brush seal is provided. The brush seal may comprise an annular backing plate and a first bristle pack coupled to the annular backing plate. The first bristle pack may be oriented in an axial direction. A second bristle pack may be coupled to the first bristle pack and oriented in the axial direction. A bristle of the first bristle pack may have a greater diameter than a bristle of the second bristle pack. A retention structure may be coupled to the second bristle pack.
