Abstract: 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.

Abstract: 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.

Abstract: A method of installing a bracket to an engine casing of a gas turbine engine includes attaching a first mount segment of a first bracket to an auxiliary component and attaching a second mount segment of the first bracket to the engine casing. In one exemplary embodiment, the method can include attaching a second bracket to the auxiliary component on an opposite side of the auxiliary component from the first bracket.

Abstract: 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.
