Center fuselage bellows

摘要

A sealing assembly is provided in an airframe of aircraft. The sealing assembly includes, but is not limited to a resilient and yet stiff enough bellows body that is attachable to the fuselage of the aircraft and is further attachable to a center wing box of the aircraft. The sealing assembly seals off a gap between the fuselage and the center wing box so as to allow maintaining pressure in the fuselage if the fuselage is pressurized. The bellows body is a composite and is designed to sustain exposure to tear and wear and exposure to a high and low temperatures as well as exposure to chemicals used during operation of the aircraft.

主权项

1. A sealing assembly comprising:
an elongate bellows body having a first end portion and a second end portion coupled together to form a closed ring and the ring forms a bellows, the bellows configured to attach to an airframe of an aircraft, the bellows further configured to seal off a gap in the airframe to allow pressurizing the airframe, when attached to the airframe; a first mounting member; a second mounting member; a first side portion of the bellows configured to attach via the first mounting member to the airframe; a first contoured portion of the first mounting member configured to accommodate the first side portion of the bellows; a mounting portion of the first mounting member configured to attach to the airframe; a second side portion of the bellows configured to attach via the second mounting member to the airframe; a second contoured portion of the second mounting member configured to accommodate the second side portion of the bellows; and a second mounting portion of the second mounting member configured to attach to the airframe, wherein the first contoured portion and the second contoured portion each comprise a crimped terminal portion, the crimped terminal portion crimped to curl away from the bellows when the bellows is attached to the airframe.
