Abstract: A composite structure, including a laminate that includes a set of plies, the laminate extending between a first edge and a second edge and including a rising ramp and a falling ramp. The rising ramp includes a starting point and an upper point and the falling ramp includes the upper point and an end point. Plies are partially located over their preceding ply and alternatively extend from the first edge or the second edge and are shorter than the ply located before the preceding ply so that their ends are stepped successively until they reach the top of the ramp.

Abstract: A flight control surface comprising a main body comprising an upper and lower cover, upper and lower skins and a core member, a prolongation of their length over the length of the core member defining a stepped area. A trailing edge of the control surface comprises a U-shaped profile enclosing the prolongation, the U-shaped profile extending towards the main body in the chordwise direction up to the stepped area and comprising a section that progressively decreases. The trailing edge comprises a first and a second set of rivets located in the prolongation, the first set of rivets joining the upper and lower covers and the second set of rivets joining the U-shaped profile, the upper covers and the lower covers.

Abstract: A device and a process for manufacturing a composite part, the device comprising four molding mandrels that can be arranged in a mold arrangement in which they form a mold for the composite part, as well as a locking mandrel configured to lock the molding mandrels in the mold arrangement and to be extracted from between the molding mandrels to release the molding mandrels from their mold arrangement. The locking mandrel extends from one longitudinal end of the molding mandrels to another opposite longitudinal end of the molding mandrels.
