Abstract: A return air bridge for use in an aircraft assembly includes an inboard portion configured to couple to a sidewall assembly at a bottom edge of the sidewall assembly and an outboard portion configured to couple to a structural member. The return air bridge also includes at least one support coupling the inboard portion to the outboard portion such that a return air flow path is defined between the inboard portion and the outboard portion. The outboard portion comprises a plate configured to direct an air flow along the return air flow path upwardly with respect to the bottom edge of the sidewall assembly.

Abstract: Systems and methods are provided for securing aircraft sidewall. One embodiment comprises a hanger for supporting sections of sidewall for an aircraft. The hanger includes an elongated vertical member that attaches to a frame of the aircraft, and sets of keyholes that are each arranged in a vertical pattern along the member and that are each configured to support a corresponding section of sidewall of the aircraft. Each keyhole includes a receptacle dimensioned to receive a fitting from a section of sidewall, and a slot dimensioned to slidably accept the fitting via the receptacle to secure the fitting in place. The slot size of keyholes in each set varies from one end of the vertical pattern to another end of the vertical pattern.

Abstract: The present disclosure is generally directed to a method of operation for a convertible door system including a door accessible compartment having a moveable dividing wall that substantially divides the compartment into a first and a second sub-compartment. A first door assembly, configured to allow access to the first sub-compartment, is disposed between a first of two opposing sidewalls and the moveable dividing wall. A second door assembly, configured to allow access to the second sub-compartment, is disposed between a second of the two opposing sidewalls and the moveable dividing wall. A first and a second hinge assembly are adapted to rotationally join the first and second door assembly to respective opposing sidewalls. A third hinge assembly is adapted to rotationally join the moveable dividing wall to either the first door assembly or the second door assembly.

Abstract: An apparatus, system, and method includes a socket having a substantially spherical inner contour being accessible via an opening. A member having a partial spherical shape substantially similar to the spherical inner contour. A cross-sectional profile of the member is adapted to pass through the opening into the socket and to remain uncoupled with the socket when the socket and the member are in a first relative orientation. The member is further adapted to couple with the socket when the member is in the socket and in a second relative orientation with the socket.

Abstract: Aircraft frames having multiple bracket mounting holes, corresponding brackets, and associated methods are disclosed. An aircraft frame member in accordance with one embodiment of the invention includes multiple sets of mounting holes, each set having one or more mounting holes. Brackets in accordance with an embodiment of the invention can be attached to either of at least two of the sets of mounting holes, for example, using snap fit attachment devices or other attachment devices. Each bracket can support one or more components (e.g., insulation, wiring, ECS ducting) relative to the aircraft frame member. The bracket can also span between two or more aircraft frame members. Each bracket can be installed in any of a variety of positions without the use of tools and can support any of a variety of devices. Accordingly, the time and cost associated with manufacturing, inventorying, installing and repositioning the brackets and the devices they support can be reduced.

Abstract: An insulation baffle for a mobile platform. The baffle is secured to a structure separating different lobes of the mobile platform. The baffle includes a main body portion and at least one blow out portion. A perimeter of the blow out portion is defined by at least one recess. The recess also forms a web portion that connects the blow out portion with the main body portion. A depth of the recess is predetermined such that the web portion formed by the recess will sever when a pressure differential between the different lobes exceeds a predetermined threshold. When the web portion severs at least a section of the blow out portion separates from the main body portion to air to pass between the lobes so that the pressure differential is reduced to approximately zero.

Abstract: An insulated wall for a mobile platform is formed from at least two layers. A first layer includes an insulation material. A second layer includes a flexible material having an outer face with a decorative pattern and an inner face attached to the first layer. The wall is mounted in the mobile platform with the outer face of the second layer having the decorative pattern forming a mobile platform innermost facing surface. By attaching a flexible material layer to the insulation material, the insulated wall can be formed into rolls and rolled out during installation in a single step. In another embodiment, fasteners are preinstalled in the wall for fastening the wall to the mobile platform. In yet another embodiment, a method for insulating a compartment of a mobile platform is provided.
