Abstract
An arrangement for the electrical operation of a door of an aircraft, in particular an electrical drive arrangement for the operation of cabin doors of commercial aircraft. The object of finding a new option for operating the doors of aircraft which guarantees an electrical operation of the door with high reliability and a minimum of weight is met by an arrangement for the electrical operation of a door of an aircraft by providing an electrically powered driven shaft for the operation of the door which is coupled to at least one lever arm of the door mechanism so that it rotates together with it and the rotation of which pivots the lever arm of the door mechanism by a predetermined angle. For this, at least two electrical drives independent of each other act on the driven shaft, wherein these drives are both attached to a structural part--relative to which the lever arm of the door mechanism is pivoted--via a coupling mechanism to take up torque opposing the direction of rotation, the coupling mechanism being capable of being uncoupled in direction of the rotation of each drive.
