Abstract
A gas turbine engine includes an engine static structure. A fairing is supported relative to the engine static structure and configured to provide a flow path surface of a flow path extending in an axial direction. A seal plate has first and second ends radially spaced from one another with respect to the axial direction. The first end is operatively secured to the engine static structure. The second end is configured to seal relative to the fairing. The seal plate includes a portion between the first and second ends that extends substantially in the axial direction and configured to permit the second end to move away from the fairing in the axial direction relative to the first end in response to thermal growth.

A gas turbine engine comprising:
- an engine static structure;
- a fairing supported relative to the engine static structure and configured to provide a flow path surface of a flow path extending in an axial direction;
- and
- a seal plate having first and second ends radially spaced from one another with respect to the axial direction, the first end operatively secured to the engine static structure, and the second end configured to seal relative to the fairing, wherein the seal plate includes, first, second and third portions, wherein the first portion is transverse to the second portion and the second portion is transverse to the third portion, the second portion is arranged between the first and second ends extending substantially in the axial direction and configured to permit the second end to move away from the fairing in the axial direction relative to the first end in response to thermal growth, wherein the third portion extends from the second portion to a flange on the second end, the flange extends in the axial direction, and the third portion is canted forward toward the fairing, and the first portion extends to the first end.
