Abstract: A damping arrangement comprises a drive member arranged to be driven for angular movement relative to a housing by a motor, and a damping device independent of the motor and operable to damp oscillating motion of the drive member relative to the housing.

Abstract: An actuator comprises a screw shaft, a nut translatable along the shaft between a retracted position and an extended position, a tine component carried by the nut, the tine component including tine fingers formed with projections each being engageable with a formation provided on a housing when the nut occupies its extended position to secure the nut against axial movement, and a lock member engageable with the tine fingers to restrict radial movement of the tine fingers.

Abstract: A clutch arrangement, especially adapted for use in an aircraft nose wheel landing gear steering arrangement, includes a rotatable drive input, a rotatable output, and an epicyclic gear arrangement, and a carrier upon which the planet gears are mounted, the drive input being connected to the ring gear of the gear arrangement or the carrier, the output being connected to the other of the ring gear or the carrier, and a clutch operable to control relative rotation between the ring gear and the sun gear and to direct the major portion of the torque being transmitted therethrough the first of two transmission paths.

Abstract: A torque limiter device for an aircraft wing-mounted flap includes a drive input, an output rotatable in response to rotation of the drive input, and a roller-jammer operable in the event that the torque transmitted between the drive input and the output exceeds a predetermined level to apply a braking load to the drive input and/or the output, and a brake device operable to apply a braking load to the roller-jammer device to cause activation thereof.

Abstract: A landing gear assembly comprises a wheel support housing rotatably connected to a support member, the wheel support housing containing an electrically powered motor operable to adjust the angular position of the wheel support housing relative to the support member.

Abstract: A clutch arrangement comprises a rotatable drive input, a rotatable output, and an epicyclic gear arrangement comprising a ring gear, a series of planet gears meshing with the ring gear, a sun gear meshing with the planet gears, and a carrier upon which the planet gears are mounted, the drive input being connected to one of the ring gear and the carrier, the output being connected to the other of the ring gear and the carrier, and a clutch device operable to control relative rotation between the ring gear and the sun gear. The invention also relates to a nosewheel landing gear steering arrangement including such a clutch arrangement.
