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.
Claims11
A system for opening and closing at least one hatch of a landing gear bay of an aircraft, between a closing position in which said at least one hatch is configured to allow at least in part the closing of the landing gear bay and provide at least partial continuity with an outer wall of the aircraft, and an opening position in which said at least one hatch opens the landing gear bay and is displaced along a substantially longitudinal direction of the aircraft, said opening and closing system comprising:
- at least one proximal guide rod having a first end that is pivotally fastened, about a transversal direction of the aircraft, to said at least one hatch, and a second end that is pivotally fastened, about the transversal direction of the aircraft, to an internal stationary structure of the landing gear bay;
- at least one distal guide rod having a first end that is pivotally fastened, about the transversal direction of the aircraft, to said at least one hatch, and a second end that is pivotally fastened, about the transversal direction of the aircraft, to an internal stationary structure of the landing gear bay, said at least one proximal guide rod and distal guide rod being arranged to form a deformable parallelogram type hinge;
- and
- at least one drive rod having a first end that is hingeably fastened to said at least one hatch, and a second end that is hingeably fastened to a landing gear leg.
