In one embodiment, an aircraft comprises a plurality of hoop frame support members and a landing gear enclosure comprising a curved surface. The plurality of support frame support members abut against and extend over the curved surface to provide support to the landing gear enclosure. In another embodiment, loads are transferred from a landing gear strut through a strut fitting, through at least one inner surface of the landing gear enclosure, through at least one outer surface of the landing gear enclosure, and into the plurality of hoop frame support members.

The invention claimed is: 1. An aircraft comprising a plurality of spaced-apart hoop frame support members, each hoop frame support member forming a loop extending within a pressurized fuselage, the landing gear enclosure comprising substantially straight side-surfaces and a concave dome top curved surface extending away from the substantially straight side-surfaces, the substantially straight side-surfaces and the concave dome top curved defining an unpressurized cavity within the landing gear enclosure for housing retracted landing gear within the fuselage, wherein the plurality of spaced-apart hoop frame support members abut against and extend over and around the cavity, the substantially straight side-surfaces, and the concave dome top curved surface of the landing gear enclosure to provide support to the landing gear enclosure. 2. The aircraft of claim 1 wherein the plurality of hoop frame support members are made of at least one of Titanium and Aluminum. 3. The aircraft of claim 1 wherein each of the plurality of hoop frame support members forms a continuous loop and carry fuselage loads of the aircraft independently from the landing gear enclosure. 4. The aircraft of claim 1 wherein the plurality of hoop frame support members are defined by holes to run electrical components through. 5. The aircraft of claim 1 wherein three hoop frame support members abut against and extend over and around the side-surfaces and the top curved surface of the landing gear enclosure. 6. The aircraft of claim 1 wherein the aircraft is made of a composite. 7. The aircraft of claim 1 wherein at least one inner surface of the landing gear enclosure is compressed against at least one of a surface of at least one of the hoop frame support members and a fitting member as a result of a pressure differential. 8. The aircraft of claim 7 wherein peripheral edges of the landing gear enclosure are compressed against the surface of the at least one hoop frame support member and the fitting member as a result of the pressure differential. 9. The aircraft of claim 1 wherein the landing gear enclosure is made of composite materials. 10. A landing gear enclosure comprising a concave dome-shaped top curved surface extending away from substantially straight side-surfaces, the concave dome-shaped top curved surface and the substantially straight side-surfaces defining an unpressurized cavity within the landing gear enclosure for housing retracted landing gear within a pressurized fuselage of an aircraft, the concave dome-shaped top curved surface and the substantially straight side-surfaces each being abutted against and under a plurality of hoop frame support members, extending within the pressurized fuselage of an aircraft, in order to provide support to the landing gear enclosure. 11. The landing gear enclosure of claim 10 wherein the dome-shaped, top curved surface is supported by the plurality of hoop frame support members of a composite aircraft which independently carry fuselage loads independently from the landing gear enclosure. 12. The landing gear enclosure of claim 10 wherein peripheral edges of the landing gear enclosure are compressed against at least one of the hoop frame support members and a fitting member as a result of a pressure differential. 13. The landing gear enclosure of claim 10 wherein the landing gear enclosure is made of composite materials. 14. A method of installing a landing gear enclosure in an aircraft comprising: providing an aircraft comprising a plurality of hoop frame support members forming loops within a pressurized fuselage of the aircraft; providing a landing gear enclosure comprising substantially straight side-surfaces and a concave dome top curved surface extending away from the substantially straight side-surfaces, the substantially straight side-surfaces and the concave dome top curved surface defining an unpressurized cavity; and abutting the substantially straight side-surfaces and the concave dome top curved surface of the landing gear enclosure against and under the plurality of hoop frame support members in order to support the landing gear enclosure. 15. The method of claim 14 wherein the hoop frame support members form continuous loops and carry fuselage loads of the aircraft independently from the landing gear enclosure. 16. The method of claim 14 wherein the aircraft is made of a composite. 17. The method of claim 14 further comprising the step of compressing peripheral edges of the landing gear enclosure against at least one of a surface of one of the hoop frame support members and a surface of a fitting member. 18. The method of claim 17 wherein the compressing step is caused by a pressure differential on the landing gear enclosure. 19. The method of claim 14 wherein the landing gear enclosure is made of composite materials.
