Each one of the at least one primary drive station is adapted for moving the respective primary lever on driving the shaft connection, and each one of the at least one secondary unit comprises a selectively activatable brake, such that the secondary lever follows the motion of the one of the at least one high lift surface when the brake is deactivated. | 12-17-2015 |
20160028332 | POSITION AND SPEED SYNCHRONIZATION FOR A DUAL LINEAR ACTUATOR FLAP SYSTEM - A method for controlling a first motor and a second motor to synchronize respective positions of the first motor and the second motor may comprise comparing the positions to determine a position difference, incrementally increasing a speed of one of the first motor and the second motor and incrementally decreasing a speed of the other of the first motor and the second motor according to the position difference, and repeating the incrementally increasing and incrementally decreasing until the respective positions are synchronized. Additionally, motor current limiting may be applied by reducing the target speed of the motor(s) with high applied torque(s), which may result in a position difference between the two motors subject to synchronization/correction. If current limiting is applied to one or both of the motors, speed synchronization may be applied in addition to position-based synchronization. | 01-28-2016 |
20160031546 | LIFT-REDUCING APPARATUS FOR AIRCRAFT WINGS - Modern aircraft wings generally have a lower surface the rear part of which is concave over at least some of its length, for additional lift. Sometimes it is desirable to reduce the wing lift, for instance during turbulence. To this end the wing | 02-04-2016 |
20160083082 | LINK FOR COUPLING AN AIRCRAFT LIFT DEVICE TO A TRACK - A link for coupling an aircraft lift device to a track that is deployable about an axis of rotation. The link includes a track member to be fixed relative to the track, a lift device member to be fixed relative to the lift device, and an intermediate member that couples the track member to the lift device member. The link is configured to allow for sliding movement of the lift device member relative to the track member such that the lift device is slidable along a linear path relative to the track in a direction of the axis of rotation of the track. | 03-24-2016 |
20160144947 | HIGH-LIFT SYSTEM - A high-lift system for an aircraft includes a high-lift flap which is arranged on the wing of the aircraft and is mounted on a carriage coupled to the wing, the carriage being displaceably mounted on a track by means of a high-lift bearing. The high-lift bearing includes a plain bearing. | 05-26-2016 |
