Abstract

A front landing gear module for an aircraft is disclosed including an open box provided with at least one door and containing a deployable front landing gear. The module may be a one-piece module and also including an attachment system intended to attach it on the aircraft, which allows the module to be manufactured in advance, before it is integrated as an individual assembly into the structure of the fuselage of the aircraft.

First claim

The invention claimed is:

1. A front landing gear module for an aircraft, comprising:
an open box provided with at least one door configured to be able to be opened and closed,
the box containing a deployable front landing gear configured to be deployed through the door,
an attachment system configured to attach the front landing gear module on the aircraft and comprises link elements, to which at least the front landing gear is linked, said link elements being configured to be able to be linked to the aircraft, and
a plurality of strengthening elements, with each of said strengthening elements linking one of said link elements to said box.

2. The front landing gear module according to claim 1 , wherein the box has an aerodynamic outer shape corresponding to a predetermined shape for a bottom front part of a fuselage of the aircraft.

3. The front landing gear module according to claim 1 , wherein the box further comprises a door frame and two adjacent doors, each linked to a part of the door frame.

4. The front landing gear module according to claim 1 , wherein the attachment system is configured to provide a supplementary attachment of an upper edge of the box, surrounding the opening of the open box.

5. The front landing gear module according to claim 1 , wherein the box comprises a flat front bulkhead.

6. The front landing gear module according claim 1 , wherein the box further includes at least one access hatch granting access to the inside of the box.

7. An aircraft comprising a front landing gear module according to claim 1 .

8. The aircraft according to claim 7 , further comprising a bay at the front under a cockpit, in which bay the front landing gear module is attached.

9. The aircraft according to claim 8 , wherein the wall of the bay is formed by a plurality of adjacent sectors.

10. The aircraft according to claim 9 , wherein the wall of the bay has a curved shape.

11. The aircraft according to claim 7 , further comprising in the bay front and rear attachment supports for the link elements, and attachment supports for a door frame.

12. The aircraft according to claim 7 , comprising a supplementary attachment of the upper edge of the box on the fuselage of the aircraft.

13. The aircraft according to claim 7 , wherein a front bulkhead of the front landing gear module matches a front bulkhead of the fuselage of the aircraft, the front bulkheads forming a single wall when the front landing gear module is attached on the aircraft.

14. The aircraft according to claim 7 , wherein an aerodynamic outer wall of the box of the front landing gear module corresponds to a bottom front part of the fuselage of the aircraft.

15. A one-piece aircraft front landing gear module, comprising:
an open box provided with at least one door configured to be able to be opened and closed,
the box containing a deployable front landing gear configured to be deployed through the door,
an attachment system configured to attach the front landing gear module on the aircraft and comprises link elements, to which at least the front landing gear is linked, said link elements being configured to be able to be linked to the aircraft,
a plurality of strengthening elements, with each of said strengthening elements linking one of said link element to said box, and
wherein the box includes an aerodynamic outer surface corresponding to a predetermined shape for a bottom front part of a fuselage of the aircraft.

16. A front landing gear module for an aircraft, comprising:
a housing bounding an opening provided with at least one door configured to open and close,
a front aircraft landing gear,
a plurality of links operably securing the front aircraft landing gear to and within the housing, the front landing gear being configured to deploy through the at least one door, and
an attachment system configured to attach the housing to the aircraft.

17. The front landing gear module according to claim 16 , wherein the housing has an aerodynamic outer shape corresponding to a predetermined shape for a bottom front part of a fuselage of the aircraft.

18. The front landing gear module according to claim 16 , wherein the housing comprises a flat front bulkhead.

19. The front landing gear module according to claim 16 , wherein the housing further includes at least one access hatch granting access to the inside of the box.

20. An aircraft comprising a front landing gear module according to claim 16 .
