A drive system for the flaps / slats of an aircraft wing comprises drive shafts which are connected to the flaps, and comprises one or more servo motor units 30 connected to the drive shafts, wherein the drive shafts can be selectively coupled with one another. Ideally, a first drive shaft 12 is connected to a first flap 10 while a second drive shaft 22 is connected to a second flap 20, and a clutch mechanism 50 is selectively operable to connect the drive shafts in series. A main power unit 30 is provided preferably at one end of the drive shafts / transmission rods, while a secondary one 40 is provided at the opposite end for operating one of the flaps individually. When a flap is to be operated individually, the clutch mechanism separates, while brakes 60 release one flap while locking the other against movement. In this way, the camber of the wing/s can be altered in sync, or asymmetrically. |
