Embodiment Construction

[0063] As explained above, the object of the present application is the opening and closing system of the undercarriage compartment of an aircraft 1 , and also the undercarriage compartment comprising such a system.

[0064] as in figure 1 As indicated above, the aircraft 1 comprises a nose gear comprising a set of wheels (not given reference numerals) mounted at one end of a gear strut 2 .

[0065] In flight, when it is not in use, the undercarriage is retracted into a suitable housing located within the fuselage or fairing of the aircraft 1 and referred to as the undercarriage compartment 3 .

[0066] To enable its deployment, said undercarriage strut 2 is pivotally mounted on a fixed structure of the aircraft.

[0067] In order to ensure the aerodynamic profile of the fuselage in flight, said undercarriage compartment 3 is closed by a set of hatches comprising two front hatches (not shown) and one rear hatch 5 .

[0068] The front hatch serves to allow the passage of the ...

Abstract

The present disclosure provides a system for opening and closing, in a substantially longitudinal direction, at least one hatch of a landing gear bay of an aircraft. In particular, the system includes: a proximal guide rod and a distal guide rod, each having a first end pivotably attachable to the hatch, and a second end pivotably attachable to a stationary inner structure of the gear bay, and arranged such as to form a deformable parallelogram hinge; and at least one drive rod having a first end that is pivotably attachable to the hatch, and a second end that is pivotably attachable to a landing gear leg.

Description

technical field [0001] The present invention relates to a device for opening and closing the landing gear of an aircraft, and more particularly to a closing hatch, in particular a rear hatch, of such a device. Background technique [0002] A landing gear bay is a housing used to house the landing gear of an aircraft. [0003] In most aircraft used to transport goods or people, the landing gear is located within the fuselage of the aircraft and is usually closed by an opening and closing system comprising several hatches. [0004] There are several opening and closing systems. [0005] Typically, an opening and closing system, or hatch system, includes at least two main hatches, such as forward gear hatches, which are opened to allow deployment of the gear and closed when the gear is out , in order to limit aerodynamic disturbances. [0006] The system also includes at least two secondary hatches, such as aft landing gear hatches, which are opened to allow deployment of th...
