Abstract: A mechanical drive connection assembly (1) for driving in rotation a carrier shaft (2) of a structure rotating about a central axis (2a) passing through this carrier shaft (2). This connection (1) includes at least one drive ring (3a) that is secured to this carrier shaft (2) and driven in rotation in a given direction (S1) by a transmission member (4a, 4b). This transmission member is connected at one end to the drive ring (3a) by winding and at its other end to a traction device. The rotation in the opposite direction (S2) is generated by a second traction device (5) connected to the carrier shaft (2).

Abstract: Double-curved aircraft door having a pair of stops in contact over a contact area. The isobarycentre (31A) of each contact area of a first lateral edge is substantially arranged in a first plane perpendicular to the longitudinal axis (21) and the same applies to a second lateral edge. For each contact area, the normal to the contact area passing through its isobarycentre (31A, 31B) substantially passes through the axis (41) of a medium cylinder (42). For each contact area, the normal to the contact area passing through its isobarycentre (31A, 31B) forms a deflection angle with a plane perpendicular to the longitudinal axis (21), the deflection angles of all the contact areas being equal.
