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 (2) of an aircraft, the high lift system comprising a central power control unit (4) for providing rotational power by means of a transmission shaft (6); and actuator drive stations (12) coupled with the power control unit (4) and movable high lift surfaces (18); the method comprises the steps of acquiring a first rotational position of a first position pick-off unit (20) 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 (20) mechanically coupled with a driven element in at least one drive station (12), determining the number of full rotations the first position pick-off unit (20) has already accomplished between a neutral position and an intended maximum number of rotations based on an associated number of angle sections of the second position pick-off unit (20) and the actual second rotational position and multiplying the number of full rotations of the first position pick-off unit with 360° and adding the resulting full rotations angle to the measured first rotational position to acquire the first rotational position. The accuracy and the reusability of feedback position pick-off units (20) is thereby clearly improved.
