  • Patent number: 10228702
    Abstract: A method for optimizing the take-off parameters of an aircraft. The aircraft comprises a system for automatically controlling the high lift devices at the moment when the wheels of the aircraft leave the ground. The method comprises a step of selecting a first configuration of the high lift devices at the start of the take-off phase and a selection of an acceleration speed of the aircraft. The method is advantageous in that, on reception of an actual aircraft take-off detection signal, a control unit is configured to transmit a control command making it possible to bring the high lift devices into a second configuration, in which they are retracted relative to the first position, and consecutively accelerate the speed of the aircraft automatically to an acceleration speed entered by the pilot.

  • Patent number: 7226020
    Abstract: Flaps, for example leading edge flaps and/or trailing edge flaps of an aircraft wing, are driven and adjusted by respective drive units. Drive shafts of neighboring flaps are coupled to each other by a differential gear. The differential gear is thus coupled to a main drive shaft which is driven by a main drive unit. Additionally, the differential gear is coupled to a secondary drive unit. The main drive power and the secondary drive power and thus the respective flap motions are super-imposable on each other, which permits operating the flaps independently of each other or in synchronism with each other.
