A pressure bulkhead system comprises a pressure bulkhead adapted to be connected to a fuselage of a vehicle to separate a pressurized cabin space of the vehicle from an unpressurized cabin space of the vehicle, and a peripheral pressure frame to sealingly connect the pressure bulkhead to the vehicle fuselage. The peripheral pressure frame comprises an attachment section sealingly attached to an outer rim portion of a first surface of the pressure bulkhead. The first surface, when the pressure bulkhead system is installed in the vehicle, faces the unpressurized cabin space of the vehicle. A flange section is adapted to be sealingly attached to an inner surface of the vehicle fuselage and extends in a direction facing away from the first surface of the pressure bulkhead. A flexible section interconnects the attachment section and the flange section and is flexible to accommodate cabin pressure acting on the pressure bulkhead.

A fuel containment system for an aircraft is provided. The fuel containment system comprises an upper fuel barrier under a cabin floor, an aft wheel well bulkhead, an aft fuel barrier opposite the aft wheel well bulkhead, a lower fuel barrier associated with a cargo floor, and a lower fuselage skin panel. A fuel tank is created by the upper fuel barrier, the aft wheel well bulkhead, the aft fuel barrier, the lower fuel barrier, and the lower fuselage skin. The fuel tank is integrated into the aircraft and existing structural components are sealed to prevent fuel from leaking out of the integrated fuel tank.

Pressure bulkhead apparatus is disclosed. An example bulkhead apparatus includes a frame and a plurality of beams radially spaced relative to a longitudinal axis of the frame. A beam from the plurality of beams has a first end and a second end. A beam end assembly couples the second end of the beam and a stringer of a fuselage. The beam end assembly enables the second end of the beam to move relative to at least one of the frame or the stringer.

A pressure bulkhead for a pressurized vehicle such as an aircraft employs a plurality of layers of composite fiber material having uni-directional fibers arranged in a single direction within the composite fiber material. The pressure bulkhead incorporates non-traditional radial and circumferential stiffening members into a composite laminate and aligns the radial stiffening members with the direction of dominant load paths. The radial and circumferential stiffening members are interlaid between full layers of the composite fiber material. Related methods of manufacturing the pressure bulkhead include using automated fiber placement equipment to form each layer of the pressure bulkhead and discretely orient the integral stiffeners and the uni-directional fibers in each layer.
