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.
Claims17
A gas turbine engine comprising:
- a frame comprising:
- an outer radial casing;
- an inner radial casing;
- and
- a plurality of struts that extend between the inner radial casing and the outer radial casing;
- an annularly shaped fairing disposed adjacent the inner radial casing;
- a rib protruding from the annularly shaped fairing and extending in a circumferential direction;
- a heat shield connected to the inner radial casing and including a first portion and a second portion, wherein the first portion is cylindrically shaped and extends between the fairing and the inner radial casing and the second portion extends radially away from the inner radial casing and the first portion toward the fairing;
- a seal support that is connected to the inner radial casing and extends toward the outer radial casing;
- and
- a seal retained by and between the rib and the seal support.

A heat shield assembly for a gas turbine engine, comprising:
- a plurality of unitary heat shield segments, each unitary heat shield segment subtending a sector of a full ring, the unitary heat shield segment comprising:
- a mounting region;
- a cylinder portion supported from the mounting region, wherein the cylinder portion has a first edge that forms a first notch;
- and
- a flange supported from the mounting region, wherein the flange extends away from the mounting region and the cylinder portion;
- wherein the unitary heat shield segments are circumferentially spaced, each unitary heat shield segment abutting circumferentially adjacent unitary heat shield segments to form a full ring;
- and
- a frame comprising:
- an inner radial casing;
- an outer radial casing;
- and
- a plurality of struts extending from the inner radial casing to the outer radial casing to connect the inner radial casing to the outer radial casing;
- wherein notches of circumferentially adjacent unitary heat shield segments are adapted to form a socket that receives one of the struts.

A method comprising:
- disposing a plurality of unitary heat shield segments between a casing and a fairing, wherein the unitary heat shield segments are circumferentially spaced, each unitary heat shield segment subtending a sector of a full ring and abutting circumferentially adjacent unitary heat shield segments to form a full ring, and wherein the unitary heat shield segments are disposed adjacent the casing, each unitary heat shield segment disposed between two struts of a plurality of struts that extend from the casing;
- connecting the unitary segments to the casing;
- and
- attaching the segments together to form a heat shield, each of the unitary segments having a first portion positioned adjacent the casing and a second portion extending away from the casing.
