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.

Abstract: An assembly for a gas turbine engine includes a first module, a second module, and a flow discourager. The second module is connected to the first module along a joint. The flow discourager is connected to the first module and extends to be received in a notch in the second module. The flow discourager acts to direct an ingestion gas flow away from the joint between the first module and the second module.
