METHOD FOR DETERMINING THE POSITION OF A COMPONENT IN A HIGH LIFT SYSTEM OF AN AIRCRAFT, HIGH LIFT SYSTEM OF AN AIRCRAFT AND AIRCRAFT

摘要

A method for determining the position of a component in a high lift system of an aircraft, the high lift system comprising a central power control unit for providing rotational power by means of a transmission shaft; and actuator drive stations coupled with the power control unit and movable high lift surfaces. The method comprises the steps of acquiring a first rotational position of a first position pick-off unit mechanically coupled with the power control unit by means of a first gear having a first gear ratio, acquiring at least one second rotational position of at least one second position pick-off unit mechanically coupled with a driven element in at least one drive station, and determining the number of full rotations the first position pick-off unit has already accomplished between a neutral position and an intended maximum number of rotations.

1. A Method for determining the position of a component in a high lift system of an aircraft, the high lift system comprising a power control unit for providing rotational power by means of a transmission shaft; and actuator drive stations coupled with the power control unit and movable high lift surfaces; the method comprising the steps of:
acquiring a first rotational position of a first position pick-off unit mechanically coupled with the power control unit by means of a first gear having a first gear ratio, acquiring at least one second rotational position of at least one second position pick-off unit mechanically coupled with a driven element in at least one drive station, the number of full rotations the first position pick-off unit has already accomplished between a neutral position and an intended maximum number of rotations based on an associated number of angle sections of the at least one second position pick-off unit and the actual second rotational position, and multiplying the number of full rotations of the first position pick-off unit by 360° and adding the resulting full rotations angle to the measured first rotational position to acquire the first rotational position.
