Abstract

A drive system (2) for driving control surfaces (10, 12) of an aircraft comprises at least one drive unit (4), at least one main shaft (6) connectable to the at least one drive unit (4) and at least two adjusting units (8) for each control surface (10, 12) to be driven. Each adjusting unit (8) comprises a differential (14), two rotary actuators (16) and an adjustment lever (18). The differential (14) has at least one input means and two output means and is adapted to transfer torque from the at least one input means to the two output means. The input means is connectable to the main shaft (6), the two rotary actuators (16) each have a rotation input means and a motion output means. The rotation input means is connectable to one of the output means (30) of the differential (14) each and the adjustment lever (18) is connected to the motion output means of both rotary actuators (16). Thereby two load paths are realized for each adjustment lever such that a mechanical connection between adjacent control surfaces is not necessary for maintaining a certain level of redundancy.
