Abstract: An aircraft landing gear bay roof for forming a pressurization barrier between an upper pressurized compartment and a landing gear bay for the housing of a landing gear. The roof comprises a main bulkhead extending in a longitudinal direction, an inclined forward bulkhead, rigidly connected to a forward edge of the main wall, and an inclined aft bulkhead, rigidly connected to an aft edge of the main bulkhead. The forward bulkhead and the aft bulkhead each form an obtuse angle with the main bulkhead. 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.

Abstract: A double-walled tank comprising at least one connection system connecting the outer and inner enclosures and enabling them to move in relation to one another in at least a longitudinal direction parallel to an axis of displacement when in operation. The connection system has an annular linear connection between a first contact surface rigidly connected to the outer enclosure and a second contact surface rigidly connected the inner enclosure, the first and second contact surfaces arranged opposite one another and configured to be in contact with one another along a contact circle that has a center positioned on the axis of displacement.

Abstract: An aircraft landing gear bay roof, the roof forming a pressurization barrier between a pressurized upper compartment and a landing gear bay for the housing of a landing gear, comprising a roof wall forming the pressurization barrier. The roof wall is held by longitudinal gantries to which it is linked, and which extend over the entire length of the roof wall. The roof wall comprises a lower face configured to be installed inside the landing gear bay and an upper face configured to be installed outside the landing gear bay. At least one of the gantries is installed against the lower face of the roof wall.

Abstract: An aircraft comprising at least one power plant linked to an airfoil by a power plant support structure comprising a primary structure housed in an aerodynamic fairing. The power plant is formed overhanging behind the airfoil, mostly or wholly above the upper surface of the airfoil. The aircraft comprises a main landing gear comprising at least one landing gear element linked to the airfoil of the aircraft by a support structure. The primary structure and the support structure of the landing gear element are formed by a common structure. The use of such a common structure allows a general optimization of the architecture of the aircraft by virtue of the synergies between the positioning of the power plant, the primary structure of its strut, and the support structure of the main landing gear.
