Abstract:
1. An aircraft comprising a landing gear strut attached with a landing gear wheel, a strut fitting attached to the landing gear strut, the strut fitting abutting against an inner surface of an unpressurized landing gear enclosure, and a plurality of hoop frame support members forming loops extending within a pressurized fuselage of the aircraft, the unpressurized landing gear enclosure comprising side surfaces and a top surface extending away from the side surfaces, the plurality of hoop frame support members abutting against and extending over and around the side surfaces and the top surface of the unpressurized landing gear enclosure, wherein loads from the landing gear wheel transfer through the landing gear strut, through the strut fitting, through the inner surface of the unpressurized landing gear enclosure, through an outer surface of the unpressurized landing gear enclosure, and into the plurality of hoop frame support members, and wherein pressure differential loads, between the unpressurized landing gear enclosure and the pressurized fuselage, transfer from the unpressurized landing gear enclosure, through the inner and the outer surfaces of the unpressurized landing gear enclosure, and into the plurality of hoop frame support members.
