Abstract: A containment system for a gas turbine engine includes an outer containment ring having a first projection that extends radially inward and an inner containment ring having at least a second projection that extends radially outward toward the outer containment ring. The second projection is offset and spaced apart from the first projection to define a chamber in a first state. The containment system includes a lattice defined within the chamber that spans the chamber, and the lattice is integrally formed with each of the outer containment ring and the inner containment ring. The second projection is configured to interlock with the first projection in a second state.

Abstract: Outflow valve (OFV) assemblies including non-metallic frames and enhanced attachment features are provided. In embodiments, the OFV assembly includes a non-metallic frame to which at least one valve door is pivotally mounted. The non-metallic frame may, in turn, include a generally rectangular frame body, a central opening through the frame body, an outer peripheral flange extending around at least a portion of the frame body. Frame attachment interfaces are distributed or spaced around the outer peripheral flange of the non-metallic frame. The frame attachment interfaces include fastener openings and elevated platform regions, which project from an inboard side of the outer peripheral flange and through which the fastener openings extend. Base plates seat against the elevated platform regions. Fasteners engage the base plates and extend through the fastener openings to an outboard side of the outer peripheral flange to attach the OFV assembly to an aircraft fuselage.

Abstract: A labyrinth seal for a gas turbine engine is provided. The labyrinth seal includes a stator and a rotor spaced apart from the stator. The rotor includes a first tooth at a first side having a first radial height, and a second tooth between the first tooth and a second side. The second tooth has a second radial height that is different than the first radial height. The rotor includes a third tooth between the first tooth and the second side having a third radial height that is substantially the same as the first radial height. A first clearance between a first tip of the first tooth and the stator is different than a second clearance between a second tip of the second tooth and the stator, and a third clearance between a third tip of the third tooth and the stator is substantially the same as the first clearance.

Abstract: A support structure for an electronic component a chassis and a standoff that is attached to the chassis. The standoff is configured to support the electronic component and separate the electronic component at a distance away from the chassis. The standoff is configured to receive heat generated by the electronic component. The standoff includes a fluid passageway. The fluid passageway is configured to allow a cooling fluid to flow therethrough for convective heat transfer from the standoff to the cooling fluid.
