Abstract
An operating mechanism for an aircraft door performs all the door motions and locking motions for the opening and closing of the door with the aid of electric motors which operate the respective elements of the mechanism through gear drives or through spindle drives to provide the power or torque moment for the respective motion. The door sealing may be accomplished with contact hardware components or with toggle hardware components for taking up the forces resulting from the internal cabin pressure. The door is hinged to the aircraft body structure by a guiding and supporting hinging element, one end of which is hinged to the aircraft body structure while the other end is hinged to the door structure. The door swinging motions in the opening and closing directions, the door opening and closing motions and the door locking and unlocking motions are all performed by program controlled electric motors. Such motors also control the deployment of an emergency escape slide.
