摘要： A lavatory for an aircraft cabin includes a wall having a forward wall portion disposed immediately aft of and substantially conforming to an exterior aft surface of an aircraft cabin structure, such as a passenger seat, that is substantially not flat in a vertical plane. The forward wall portion includes a forward projection over an aft portion of the adjacent passenger seat. The forward wall portion can define a secondary space in the interior lavatory space, which can provide an amenity stowage space, and can include design elements providing visual space.

摘要： An apparatus and method for installing an aircraft bulkhead connector with a bulkhead is disclosed where access to only one side of the bulkhead is required. The disclosure is also applicable to installation of bulkhead connectors in aircraft fuel tanks. An aircraft bulkhead connector and installation tool is also disclosed. The bulkhead connector includes a female end portion and the installation tool includes a male end portion. The male end portion of the installation tool is removably engaged with the female end portion of the bulkhead connector, such that the installation tool protrudes beyond the female end portion of the bulkhead connector. The installation tool may be inserted through an aperture in a bulkhead and used to both position and hold the bulkhead connector during the installation process.

摘要： A panel assembly for use in a vehicle includes a first face sheet, a second face sheet, and a core layer disposed between the first and second face sheets. The core layer is defined by a base material along a first section of the panel assembly, and the core layer is defined by a honeycomb structure along a second section of the panel assembly. The first section and the second section are discrete, and the first section that includes the base material extends along a perimeter of the panel assembly.

摘要： An airframe design may include a bonded frame or assembly, and one or more components that may be removably attached to the bonded frame. The bonded frame may include struts, central bulkheads, a tail section, a plurality of wing sections, and motor mounts that are adhered together using adhesive. The one or more attachable components may include a forward fuselage, motors, propellers, motor pod fairings, stabilizer fins, and landing gear that are attached using fasteners. The bonded frame may reduce the number of parts of the airframe design and may also reduce complexity, cost, and weight, while also increasing stiffness and strength. Further, the various attachable components may facilitate fabrication, assembly, and maintenance of an aerial vehicle having the airframe design.

摘要： A fuselage for an aircraft includes a pressure deck assembly extending along a roll axis of the fuselage. The pressure deck assembly includes longitudinal beams and a pressure deck. The longitudinal beams extend lengths along the roll axis of the fuselage. The pressure deck extends between the longitudinal beams along the lengths of the longitudinal beams. The pressure deck is compliant along a pitch axis of the fuselage. The fuselage includes a bulkhead extending along a yaw axis of the fuselage. The bulkhead is joined to the pressure deck assembly at a corner joint. The fuselage includes a compression chord extending a length along the pitch axis of the fuselage. The compression chord is joined between the pressure deck assembly and the bulkhead at the corner joint such that the compression chord extends on an outside of the corner joint.

摘要： A method for making a pressure bulkhead assembly of an aircraft includes determining first locations and first orientations of a plurality of first holes, pre-drilled in an aft pressure bulkhead. The method also includes determining a first surface profile of a first interface surface of the aft pressure bulkhead and determining a second surface profile of a second interface surface of each one of a plurality of splice angles. The method also includes determining second locations and second orientations of a plurality of second holes to be drilled in each one of the plurality of splice angles corresponding to the plurality of first holes in the aft pressure bulkhead and drilling the plurality of second holes in each one of the plurality of splice angles at the second locations and second orientations.

摘要： A pressure bulkhead for the pressure-tight axial closure of a pressurized fuselage of an aircraft or spacecraft that is capable of being put under internal pressure includes dome segments, having an integrated reinforcement, in particular a peripheral reinforcement, which are in each case made integrally from a fiber-reinforced thermoplastic plastics material, and are joined to one another so as to form a pressure dome.

摘要： To prevent overheating of a structural member such as a pivot bulkhead facing a rear side of a fire wall to maintain the temperature of the structural member at allowable temperature or lower. An aircraft of the present invention includes: a fire wall resistant to flame; a structural member facing a rear side of the fire wall; and a skin surrounding the fire wall and the structural member. The structural member includes a guide member and a heat shielding member. The structural member guides, upward, air existing on the rear side of the fire wall, and the heat shielding member shields the guide member from heat radiated by the fire wall.
