A rotary geared actuator for pivotally connecting a flap to a wing of an aircraft, includes at least two adjacent actuator slices rotatably coupled together, each actuator slice including a sun gear rotatably coupled to a drive shaft and having gear teeth with a curved profile to enable movement of the actuator slices with respect to each other in conformance with bending of the wing, planetary gears in surrounding and meshing engagement with the gear teeth of the sun gear, a movable ring gear in surrounding and meshing engagement with the planetary gears, and a fixed ring gear in surrounding and meshing engagement with the planetary gears on opposite sides of the movable ring gear, each fixed ring gear being in meshing engagement only with planetary gears of one actuator slice; at least one fixed side tie bar connecting each fixed ring gear with the wing; at least one movable flap side tie bar connecting each movable ring gear with the flap; securing pins for securing each fixed side tie bar to one fixed ring gear and each movable flap side tie bar to one movable ring gear so as to permit a small axial movement between at least one tie bar and the respective fixed ring gear and/or movable ring gear; and a coupling shaft which flexibly connects an outermost sun gear of the actuator to a drive shaft.

A rotary geared actuator for pivotally connecting a flap to a wing of an aircraft, comprising: at least two adjacent actuator slices rotatably connected together, each actuator slice including: a sun gear rotatably coupled to a drive shaft, said sun gear including gear teeth extending thereabout, and said gear teeth having a curved profile to enable movement of said actuator slices with respect to each other in conformance with bending of the wing of the aircraft; a plurality of planetary gears in surrounding and meshing engagement with said first gear teeth of said sun gear; a movable ring gear in surrounding and meshing engagement with said planetary gears; and a fixed ring gear in surrounding and meshing engagement with said planetary gears and positioned on opposite sides of said movable ring gear, each fixed ring gear being in meshing engagement only with planetary gears of one said actuator slice; at least one fixed side tie bar means for connecting each said fixed ring gear with one of the wing and the flap; at least one movable flap side tie bar means for connecting each said movable ring gear with the other of the wing and the flap; securing means for securing each said fixed side tie bar means to one said fixed ring gear and said movable flap side tie bar means to one said movable ring gear so as to permit a small axial movement between at least one said tie bar means and the respective fixed ring gear and/or movable ring gear; and coupling means for coupling an outer one of said actuator slices to a drive shaft, said coupling means including: a coupling shaft having an inner end and an outer free end, said outer free end of said coupling shaft including gear teeth having a part-spherical curvature, and the drive shaft including gear teeth having a curvature conforming to the gear teeth of said coupling shaft and in meshing engagement therewith, to provide a flexible drive coupling between the drive shaft and said coupling shaft; and coupling gear means for rotatably coupling said coupling shaft to the sun gear of said outer one of said actuator slices.
