Aircraft door provided with a lever for emergency opening from outside

An aircraft door (1) having a door structure, an external wall (4) fixed to the door structure, and a lever (3) for emergency opening from the outside, which is disposed in a lever window (5) formed in the external wall (4), the lever (3) for emergency opening from the outside comprises:

• a main arm (7) provided at a first end with a handle (11) and at a second end with an opening-movement transmission shaft (12), the transmission shaft (12) being fixed with respect to the main arm (7), the main arm (7) having a first aerodynamic surface (9) extending from the handle (11) to the transmission shaft (12), the transmission shaft (12) being mounted so as to be pivotable on the door structure in such a way that the main arm (7) moves between t
• a retracted position, in which the first aerodynamic surface (9) is disposed in the contours of the lever window (5), in the continuation of the external wall (4);
• and
• a deployed position, in which the main arm (7) is outside the lever window (5), the deployed position corresponding to a configuration of activation of the emergency opening from the outside;
• a profiled cowl (8) having a second aerodynamic surface (10), the profiled cowl (8) being mounted so as to be pivotable between:
• a concealing position, in which the second aerodynamic surface (10) is aligned in the continuation of the first aerodynamic surface (9);
• a swung-out position, in which the second aerodynamic surface (10) is folded in the direction of the first aerodynamic surface (9);
• the profile cowl (8) is mounted to be pivotable on the main arm (7), and
• a driving abutment (18) suitable for rotating the profiled cowl (8) from the concealing position into the swung-out position when the main arm (7) moves from the retracted position to the deployed position.
