Abstract: A gas turbine engine assembly includes a second module interconnected with a first module along a joint such that a surface of a second radial wall faces a surface of a first radial wall, with a cavity defined in part by the first and second radial walls. A seal assembly includes a finger seal, and a seal support ring having a backing ring portion and a flow discourager arm. The backing ring is secured to one of the first radial wall and the second radial wall, and the flow discourager arm extends axially through the cavity into a recess formed in the other of the first and second radial walls. The finger seal includes a free end contacting an inner side of the flow discourager arm.

Abstract: An assembly for a gas turbine engine includes a first module, a second module, and a finger seal. The second module is connected to the first module along a joint. The finger seal is connected to the first module at a fixed end and has a free end that cantilevers from the fixed end to contact the second module. The finger seal acts to seal the joint between the first module and second module from an ingestion gas flow of the gas turbine engine.

Abstract: An assembly for a gas turbine engine includes a component and a finger seal. The component has a first surface and a second surface. The first surface has an elevation that differs from an elevation of the second surface. The finger seal is connected to the first surface and extends above the second surface. The disposition of the second surface relative to the finger seal creates a cavity below a curved portion of the finger seal.

Abstract: An assembly for a gas turbine engine includes a first casing, a second casing, and struts extending from the first casing to support the second casing. The assembly further includes a fairing and a multi-piece heat shield assembly. The fairing is disposed between the first casing and the second casing and around each of the struts. The multi-piece heat shield assembly includes a first shield extending between the first casing and the fairing, and a second shield extending between the fairing and the first casing. The multi-piece heat shield assembly further includes a third shield extending between the fairing and the second casing, and fourth and fifth heat shields extending from the third heat shield between the fairing and each of the struts.

Abstract: A seal plate for a gas turbine engine includes an annular wall provided about an axis and extending between first and second ends that are radially spaced from one another with respect to the axis. The first end includes an axially extending pilot. The second end includes an axially extending flange and an adjacent annular seal seat. The wall includes a portion between the first and second ends that extend substantially in the axial direction and is configured to permit the second end to move axially relative to the first end in response to thermal growth.

Abstract: A gas turbine engine includes a casing, a fairing, and a heat shield. The fairing is annularly shaped and disposed adjacent the casing. The heat shield is connected to the casing and includes a first portion and a second portion. The first portion is generally cylindrically shaped and extends between the fairing and the casing and the second portion extends generally radially away from the casing and the first portion toward the fairing.

Abstract: A turbine exhaust case comprises a frame, a fairing, a heat shield and a mechanical linkage. The frame comprises an outer ring, an inner ring, and a plurality of struts joining the outer ring and the inner ring. The fairing comprising a ring-strut-ring structure disposed within the frame. The heat shield is disposed between the frame and the fairing. The mechanical linkage couples the heat shield to the fairing. In one embodiment, the heat shield comprises a multi-piece heat shield that inhibits heat transfer between the frame and the fairing. In various embodiments, the mechanical linkage comprises a slip joint or a fixed joint for coupling the heat shield to the fairing.

Abstract: A multi-ply finger seal with a first ply that is subject to a first amount of deflection during operation of the gas turbine engine and a second ply that is subject to a second amount of deflection during operation of the gas turbine engine. The first amount of deflection of the first ply differs from the second amount of deflection of the second ply. The differing amounts of deflection can result from the first ply and second ply being constructed from materials that have different coefficients of thermal expansion. Additionally or alternatively, the first ply can have a stiffness that differs from the stiffness of the second ply.
