Aircraft door with circular translation guide

An aircraft door (1) comprising:

• an opening leaf (4);
• a frame (3) intended to be fastened to the fuselage (2) of the aircraft;
• a hinge structure (5) supporting the opening leaf (4) relative to the frame (3), the hinge structure (5) being connected on a first side to the frame (3) by a first pivot connection (6), and being connected on a second side to the opening leaf (4) by a second pivot connection (7), an axis of the first pivot connection (6) being parallel to an axis of the second pivot connection (7), the opening leaf (4) pivots relative to the hinge structure (5) via the second pivot connection (7) and the hinge structure (5) pivots on the frame (3) via the first pivot connection (6), such that the opening leaf (4) is movable between a closed position, in which the opening leaf (4) is in the frame (3), and an open position, in which the opening leaf (4) is open and positioned facing the fuselage (2) of the aircraft, clearing the opening of the frame (3);
• a circular-translation guide device designed to maintain an orientation of the opening leaf (4) while it is opening or closing;
• the aircraft door having:
• the hinge structure (5) is connected to the opening leaf (4) via a lifting arm (8) which allows a lifting movement of the opening leaf (4) relative to the hinge structure (5);
• the circular-translation guide device comprises a single connecting rod (11) connected to the frame (3) by one of its ends via a third pivot connection (12), the axis of which is parallel to the axis of the first pivot connection (6) and is separate from the axis, the single connecting rod (11) being connected by the other of its ends to a lever (13) by a fourth pivot connection (14), the axis of which is parallel to the axis of the first pivot connection (6) and to the axis of the third pivot connection (12);
• the lever (13) is attached to the hinge structure (5) via the second pivot connection (7), by its opposite end from the fourth pivot connection (14);
• the lever (13) extends in a first direction and comprises a first shaft (15) extending in a second direction which is parallel to the first direction and coincides with the axis of the second pivot connection (7), the hinge structure (5) being mounted on the first shaft (15) so as to be pivotable relative to the opening leaf (4);
• the lever (13) comprises a second shaft (16) extending perpendicularly to the axis of the second pivot connection (7), the lifting arm (8) being mounted in a rotatable manner on the second shaft (16).
