US 12,523,164 B2 · Fastener assembly for a gas turbine engine

Abstract

A fastener assembly for affixing two flanges to a casing of a gas turbine engine is provided. The fastener assembly includes a bolt, a fastener, and first and second spacers. The bolt has a supporting shaft extending from a head and a thread portion. The supporting shaft has a diameter larger than a diameter of the thread portion. The fastener is configured to releasably mate with the thread portion. The first spacer surrounds a portion of the thread portion and is disposed between the fastener and a first flange. The second spacer surrounds the supporting shaft and is disposed between a second flange and the bolt head. The supporting shaft engages holes in the first flange, the casing, and the second flange. At least one of the first and second spacers absorbs a portion of a tensile load acting on the bolt.

Dependent claims

A fastener assembly for affixing two flanges to a casing of a gas turbine engine, comprising:

a bolt having a head at a proximal end and a thread portion extending from a distal end opposite the proximal end, the bolt having a pitch diameter shank extending from the head and a large shank disposed between the thread portion and the pitch diameter shank;
and
a fastener configured to releasably mate with the thread portion;
wherein the fastener is configured to maintain a first flange in contact with the casing and the head of the bolt is configured to maintain a second flange in contact with the casing;
and
wherein the fastener assembly accommodates separation of at least one of the first flange and the second flange from the casing of the gas turbine engine by allowing bending of the bolt along the pitch diameter shank.
