Abstract:
1. An aeronautical high-lift system comprising a drive unit, elements for the transmission of the energy produced by said drive unit to one or more output drive stations of individual segments of landing flap/slat flap systems an overload safety device comprising at least one electrical overload sensor arranged in the drive chain between the drive unit and the one or more output drive stations, and an electronic regulator communicatively coupled with the overload sensor and the drive unit for receiving torque related signals from the overload safety device and for receiving an overload signal from the overload safety device in the event an overload is detected by the overload safety device, wherein said electronic regulator comprises means for supplying an electrical signal to the drive unit, responsive to the electronic regulator receiving said overload signal, to effect an immediate reversal operation causing a reversal of a desired value of the direction of rotation specified to the drive unit until the actual value of the speed of rotation of said drive unit assumes the value zero and maintaining the value zero by applying braking means to the drive unit, thereby rapidly reducing the load on the transmission system before the drive unit is stopped wherein applying said rapid reversal operation achieves a load reduction in the transmission system thus allowing a corresponding weight reduction in the design of the transmission system over conventional transmission systems.
