VERSTELLANORDNUNG FUER AUFTRIEBSSTEUERFLAECHEN AN EINEM FLUGZEUGFLUEGEL

摘要

A drive arrangement for lift control surfaces on an aircraft wing has a drive motor and a shaft for transmitting motion from the motor to the lift control surfaces. A control circuit is responsive to the driving positions of both the motor and the shaft, and is responsive to a predetermined level of discrepancy between these positions to operate one or more braking devices which restrain the shaft against movement.
