Problems solved by technology

[0009] However, although this configuration allows forces to be taken up by the gear wells, this configuration is not optimal with respect to the conduction of forces in the gear wells and towards the structure of the fuselage

Embodiment Construction

[0038] refer to figure 1 , presents an aircraft 100 , in this case a commercial aircraft type.

[0039] Throughout the following description, as a convention, X corresponds to the longitudinal direction of the aircraft, Y corresponds to the lateral direction, oriented transversely with respect to the longitudinal axis, and Z corresponds to the vertical or altitude direction, the three directions X, Y and Z being orthogonal to each other. pay.

[0040] Furthermore, the terms "forward" and "rear" are to be considered with respect to the forward direction of the aircraft in flight, which direction is schematically represented by arrow A.

[0041] Aircraft 100 includes a fuselage 102 to which two wings 104 are attached at fuselage section 102a.

[0042] The fuselage section 102a is special to the invention in that it comprises a gear well provided with a gear well roof according to the invention.

[0043] Fuselage section 102a is in figure 2 presented in more detail. It incl...

Abstract

The invention relates to an aircraft landing gear bay roof comprising an inclined aft bulkhead. Specifically, the invention relates to an aircraft landing gear bay roof (3) for forming a pressurization barrier between an upper pressurized compartment and a landing gear bay for the housing of a landing gear. The roof (4) comprises a main bulkhead (41) extending in a longitudinal direction (X), an inclined forward bulkhead (42), rigidly connected to a forward edge (411) of the main wall (41), and an inclined aft bulkhead (43), rigidly connected to an aft edge (412) of the main bulkhead (41). Theforward bulkhead and the aft bulkhead each form an obtuse angle with the main bulkhead (41). This configuration enables a better absorption of loads by the landing gear bay roof and a shorter and optimized path for transmission of the mechanical loads, in particular to the fuselage member to which the aft bulkhead is configured to be connected.

Description

technical field [0001] The invention relates to the structure of aircraft, in particular at their landing gear. It relates in particular to the main undercarriage wells, and more particularly to the roof of such undercarriage wells. Background technique [0002] In most aircraft known in the prior art, especially commercial passenger or cargo transport aircraft, the main gear well is formed under the fuselage of the aircraft, at a longitudinal position near the trailing edge of the aircraft's main wings. [0003] The main gear bay roof is primarily intended to ensure separation between the pressurized upper deck and the lower deck forming the gear bay for accommodating the main landing gear. [0004] This non-pressurized undercarriage well is bounded at the front by a center wing box and at the rear by a luggage compartment. [0005] The gear dome is usually attached to the upper panel of the center wing box. Therefore, the cabin roof must withstand the deformation of the...
