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.

System for opening and closing a gear bay

An aircraft structure includes a skin () that is reinforced in two directions: by a first family of stiffeners called stringers () that are arranged in the longitudinal direction of the aircraft, and by a second family of stiffeners called frames () that are arranged in planes that are perpendicular to the longitudinal direction and that ensure the taking up of orbital forces, characterized in that at least one frame () has a hollow cross-section that is delimited by a closed profile, produced for a given cross-section in a single piece, of which one portion is in contact with the skin.
