A fluid conduit for a gas turbine engine includes a first fluid conduit attachable to a second fluid conduit and securable together with a lockable connector. The connector includes a first portion including external threads and a second portion receiving the first portion and including internal threads mating to the external threads of the first portion. The internal threads include lead threads defining a first thread interface with the external threads for starting attachment of the first portion to the second portion and locking threads defining a second thread interface for locking the first portion to the second portion.

Locking fluid fittings

Aspects of the disclosure are directed to a tube assembly comprising: a first tube having a radial exterior surface, a second tube composed of a plurality of segments, the first tube co-axially nested within the second tube, at least a first spacer coupled to the first tube, and a second spacer coupled to the at least a first spacer, where a first segment of the plurality of segments is coupled to a first axial end of the second spacer, and a second segment of the plurality of segments is coupled to a second axial end of the second spacer.

Double walled tube and manufacture thereof

The present disclosure includes active clearance control systems including improved cooling manifolds. Such improved manifolds may utilize multiple cooling zones to provide varied levels of cooling to an engine case.

Active clearance control systems

A mount system for an auxiliary component includes two side brackets and a top bracket for rigidly attaching an auxiliary component to an engine casing. Each side bracket defines mount segments, a deformable member and two retainer members between the mount segment. The deformable member plastically deforms during a fan-blade out event, thereby absorbing a majority of the high shock load experienced on the auxiliary component. The retainer members maintain the attachment between the auxiliary component and the engine casing subsequent to the fan-blade out event.
