The present invention relates to a front aircraft part (1) comprising a non-pressurised landing gear housing zone (28) designed to house a front landing gear (30) in a retracted state, as well as a pressurised zone (2) adjacent to the non-pressurised landing gear housing zone. According to the inven
The present invention relates to a front aircraft part (1) comprising a non-pressurised landing gear housing zone (28) designed to house a front landing gear (30) in a retracted state, as well as a pressurised zone (2) adjacent to the non-pressurised landing gear housing zone. According to the invention, the pressurised zone is delimited by a set of walls among which only a substantially flat-shaped sealed partition wall (10) also participates in delimiting the non-pressurised landing gear housing zone (28).

The invention claimed is: 1. A front aircraft part, comprising: a non-pressurised landing gear housing zone to house a front landing gear in a retracted state thereof; and a pressurised zone adjacent to said non-pressurised landing gear housing zone, wherein said pressurised zone is delimited by a
The invention claimed is: 1. A front aircraft part, comprising: a non-pressurised landing gear housing zone to house a front landing gear in a retracted state thereof; and a pressurised zone adjacent to said non-pressurised landing gear housing zone, wherein said pressurised zone is delimited by a set of walls among which only a substantially flat-shaped sealed partition wall delimits said non-pressurised landing gear housing zone, said substantially flat-shaped sealed partition wall delimiting, at a top part thereof, a non-pressurised radome zone separated from said non-pressurised landing gear housing zone by an intermediate partition, a front end of said intermediate partition being fixedly attached to an aerodynamic fuselage cladding, and a rear end of said intermediate partition being fixedly attached to said substantially flat-shaped sealed partition wall, and said substantially flat-shaped sealed partition wall is fixedly attached to a front end of a separation floor between a top pressurised compartment and an under-floor pressured compartment, both of said compartments belonging to said pressurised zone. 2. The front aircraft part according to claim 1, wherein a bottom end of said substantially flat-shaped sealed partition wall is fixedly attached to said aerodynamic fuselage cladding, said sealed partition wall extending forward through said front aircraft part, from a bottom end of said sealed partition wall. 3. The front aircraft part according to claim 1, wherein said non-pressurised landing gear housing zone is delimited by a portion of said substantially flat-shaped sealed partition wall situated under said separation floor. 4. The front aircraft part according to claim 3, wherein a top part of said portion of the substantially flat-shaped sealed partition wall situated under said separation floor is fixedly attached to a front end of the separation floor, and a remaining part of said portion of the substantially flat-shaped sealed partition wall situated under said separation floor is attached fixedly to an aerodynamic fuselage cladding. 5. The front aircraft part according to claim 1, wherein said substantially flat-shaped sealed partition wall is fixedly attached over an entire periphery thereof to an aerodynamic fuselage cladding. 6. The front aircraft part according to claim 1, wherein the rear end of said intermediate partition is fixedly attached to said substantially flat-shaped sealed partition wall, so as to be situated in line with a separation floor. 7. The front aircraft part according to claim 1, wherein said substantially flat-shaped sealed partition wall is produced from composite material. 8. The front aircraft part according to claim 1, further comprising a front landing gear provided with a deployable extension carrying a set of tires at one end and being articulated at an other end on an articulation arranged to a rear of an aircraft with respect to said set of tires when said front landing gear is housed in the retracted state inside said non-pressurised landing gear housing zone. 9. The front aircraft part according to claim 1, wherein said deployable extension is formed by a telescopic mechanism including at least three arms fitted in. 10. The front aircraft part according to claim 1, wherein said substantially flat-shaped sealed partition wall is inclined with respect to the separation floor. 11. The front aircraft part according to claim 10, wherein said substantially flat-shaped sealed partition wall is inclined between 20° and 50° with respect to the separation floor. 12. The front aircraft part according to claim 1, wherein upper and lower ends of said substantially flat-shaped sealed partition wall are fixedly attached to an aerodynamic fuselage cladding such that said substantially flat-shaped sealed partition wall seals said pressurized zone from said non-pressurised landing gear housing zone and said non-pressurised radome zone. 13. A front aircraft part, comprising: a non-pressurised zone including a landing gear housing zone to house a front landing gear in a retracted state thereof and a radome zone separated from said landing gear housing zone by an intermediate partition; and a pressurised zone adjacent to and separated from said non-pressurised zone by a substantially flat sealed partition wall, said substantially flat sealed partition wall sealing a front end of the pressurised zone, wherein said non-pressurised zone is delimited by walls of an aircraft fuselage and said substantially flat sealed partition wall, upper and lower ends of said substantially flat sealed partition wall are fixedly attached to an aerodynamic fuselage cladding, a front end of said intermediate partition is fixedly attached to an aerodynamic fuselage cladding, a rear end of said intermediate partition is fixedly attached to said substantially flat- shaped sealed partition wall, and said substantially flat sealed partition wall is fixedly attached to a front end of a separation floor separating a top compartment and an under-floor compartment, both of said compartments belonging to said pressurised zone. 14. The front aircraft part according to claim 13, wherein said substantially flat sealed partition wall is inclined with respect to the separation floor. 15. The front aircraft part according to claim 14, wherein said substantially flat-shaped sealed partition wall is inclined between 20° and 50° with respect to the separation floor.
