Abstract
The present invention relates to an aircraft high-lift system with at least one drive unit for operating the high-lift systems of the half wings (half-wing systems) and with at least one overload protection to avoid undesirably high operating torques in the half-wing systems, wherein the overload protection includes a comparator, by means of which the instantaneous values of the operating torques of the half-wing systems are compared and/or a condition caused by the difference of the operating torques is detected, and a limiter connected with the comparator, by means of which the drive unit is blocked, shut down or deactivated, and/or the torque of the drive unit is dissipated into the aircraft structure, when the difference of the operating torques determined in the comparator exceeds a limit value.
Claims20
An aircraft high-lift system comprising
- (i) at least one drive unit for operating the high-lift systems of a pair of half wings on opposite sides of an aircraft, and
- (ii) at least one overload protection to avoid undesirably high operating torques in the pair of half wings,
- wherein the overload protection includes
- (A) a comparator, by which the instantaneous values of the operating torques of the pair of half wings are compared or a condition caused by the difference of the operating torques is detected, and
- (B) a limiter connected with the comparator, by which the drive unit is blocked, shut down or deactivated or the torque of the drive unit is dissipated into the aircraft structure, when the difference of the operating torques determined in the comparator exceeds a limit value.
The aircraft high-lift system according to any one of the preceding claims, characterized in that no torque limiters at the root of the pair of half wings are provided.
