Abstract
A module includes two main landing gears and a landing gear bay containing the landing gears. The bay has two lateral walls, a roof wall, a front wall and a rear wall. The roof wall, the front wall and the rear wall together form a pressurization barrier between the bay and a pressurized compartment. By virtue of the landing gear module, it is now possible to assemble and test the main landing gears and the one or more doors and the fairing before they are installed on the aircraft.

An aircraft main landing gear module for an aircraft, the aircraft main landing gear module comprising:
- two main landing gears configured to be deployed or retracted alternately or simultaneously;
- and
- a landing gear bay containing the landing gears,
- the landing gear bay comprising:
- two lateral walls;
- a roof wall;
- a front wall;
- and
- a rear wall;
- wherein the roof wall, the front wall, and the rear wall are configured to form together a pressurization barrier between the landing gear bay and a pressurized compartment;
- and
- wherein the two lateral walls, the roof wall, the front wall, and the rear wall are formed such that the landing gear bay is formed as a complete module that is independent from a center wing box of the aircraft, such that the aircraft main landing pear module is mountable on the aircraft in a modular manner, separate from the center wing box.
A central aircraft fuselage part, comprising, in order from a front towards a rear of an aircraft:
- a front section of the central fuselage part;
- a center wing box comprising at least a front wall, a rear wall and a roof wall that together form a pressurization barrier;
- a central section of the central fuselage part comprising an intermediate wall forming a pressurization barrier, the intermediate wall comprising a front end and a rear end, the front end being connected to an edge of the rear wall of the center wing box;
- a landing gear module comprising:
- two main landing gears configured to be deployed or retracted alternately or simultaneously;
- a landing gear bay containing the landing gears, the landing gear bay comprising:
- two lateral walls;
- a roof wall;
- a front wall;
- and
- a rear wall;
- wherein the roof wall, the front wall and the rear wall are configured to form together a pressurization barrier between the landing gear bay and a pressurized compartment, and
- wherein the rear end of the intermediate wall is connected to an edge of the front wall of the landing gear bay;
- a rear section of the central fuselage part;
- and
- a keel beam, to which the front section, the center wing box, the central section, and the landing gear module are fastened.
