A splined coupling assembly includes: a transfer gear having a first end, a second end opposite the first end, and a plurality of splines at the first end. The splined coupling assembly also includes a transfer housing having a first side, a second side opposite the first side, and a tubular portion located at the second side. The tubular portion includes a plurality of splines. The plurality of splines of the transfer housing are configured to mesh with the plurality of splines of the transfer gear. The splined coupling assembly further includes a shear ring located in a shear ring groove in the tubular portion- and a retainer configured to retain the shear ring within the shear ring grove.

Splined coupling

A quick connect and disconnect arrangement for a cable comprises a housing for holding the cable. The housing comprises a first section and a second section. One of the first section and the second section comprises a protruding lug having an aperture therein and the other of the first section and the second section comprises a locking system. The locking system comprises a channel, an opening disposed along a portion of the channel and for receiving the lug, and a bolt configured to move within the channel. When, in use, the housing is closed around the cable, the lug is positioned in the opening, the channel is aligned with the aperture and the bolt is configured to move within the channel in order to engage with the aperture and thereby retain the lug in the opening.

Control cable quick disconnect

The exit area of a nozzle assembly is varied by translating a ring assembly located at a rear of the engine nacelle. The ring may be axially translatable along the axis of the engine. As the ring translates, the trailing edge of the ring defines a variable nozzle exit area. Translation of the ring creates an upstream exit at a leading edge of the ring assembly. The upstream exit can be used to bleed or otherwise spill flow excess from the engine bypass duct. As the engine operates in various flight conditions, the ring can be translated to obtain lower fan pressure ratios and thereby increase the efficiency of the engine. Fairings partially enclose actuator components for reduced drag.

Variable area fan nozzle with bypass flow

A variable area fan nozzle assembly for a turbofan engine includes a nacelle having an aft edge and a translating thrust reverser sleeve with a trailing edge. The thrust reverser sleeve is movably disposed aft of the nacelle's aft edge and is movable between a forward position and an aft position. A translating fan nozzle having a forward edge is movably disposed behind the trailing edge, and is movable between a stowed position and a deployed position. An upstream bypass flow exit is defined between the trailing edge and the forward edge when the fan nozzle is in the deployed position. An extendable actuation system is configured to move the fan nozzle between the stowed position and the deployed position.

Actuation system for a translating variable area fan nozzle

An actuator comprises a rotatable nut arranged to be driven for rotation by a motor, an axially translatable shaft cooperable with the nut and arranged such that rotation of the nut drives the shaft for axial movement, and a steering rack coupled to the shaft by a coupling arrangement so as to be driven for axial movement by the shaft, wherein the coupling accommodates limited relative lateral movement between the shaft and the steering rack.

Actuator

An actuator arrangement comprises a rotatable shaft, a nut mounted upon the shaft and translatable along the shaft upon rotation of the shaft relative to the nut, and a lock arrangement operable to lock the shaft and nut against relative rotation, the lock arrangement comprising a lock component mounted upon one of the shaft and the nut for axial movement relative thereto but held against angular movement relative thereto, the lock component being co-operable with an abutment provided on the other of the shaft and the nut, or a component associated therewith, to lock the shaft and nut to one another against relative rotation.

Actuator arrangement

An actuator comprises a shaftarranged to be driven for rotation by an electrically powered motor, a sleeveencircling at least part of the shaftand carrying a toothed rack formation, and a low friction screw couplingbetween the shaftand the sleeveand arranged such that rotation of the shaftdrives the sleevefor axial movement, wherein the low friction screw couplingis adjacent and aligned with the rack formation

Nose-wheel steering actuator

An actuator arrangement comprises an actuator having a rotatable drive input, a motor, and a drive transmission arrangement for transmitting rotary drive from the motor to the rotatable drive input of the actuator, wherein the transmission arrangement includes a telescopic drive coupling.

Thrust reverser and VAFN arrangement

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.

Clutch arrangement

An actuator arrangement comprises a first screw shaft, a first nut cooperating with the first screw shaft such that rotation of the first screw shaft causes the first nut to translate thereon, a second screw shaft, a second nut cooperating with the second screw shaft such that rotation of the second screw shaft causes the second nut to translate thereon, and first and second linkages connecting the first and second nuts, respectively, to an output member, rotation of the first and second screw shafts to cause translation of the first and second nuts towards one another causing extending movement of the output member and rotation of the first and second screw shafts to cause translation of the first and second nuts away from one another causing retracting movement of the output member.

An actuator is described which comprises a rotatable actuator member () and a lock arrangement () operable to lock the actuator member () against rotation, the lock arrangement () comprising an axially movable lock member (), the lock member being movable between a locked position in which it co-operates with a stop () to resist rotation of the actuator member, and a released position, and an actuation device () operable to move the lock member towards its released position.

A lock arrangement comprises a first jaw component () pivotally moveable about a pivot axis (), a second jaw component () releasably securable to the first jaw component () to form a pivotable jaw assembly (), and an actuator arrangement operable to drive the jaw assembly from a locked position to a released position.

Lock arrangement

An actuator arrangement comprises a plurality of linearly extendable actuators arranged to be driven by a common electrically driven motor, each actuator, being provided with limit stops to limit extension and/or retraction thereof, wherein the limit stops of the actuators are positioned such that a first one of the actuators has a smaller range of permitted extension than at least a second one of the actuators.

A tandem hydraulic valve comprising first and second axially aligned valve spools, a valve guide slidably receiving said valve spools to control, in use, the connection between respective ports of the valve guide, said first and second spools being formed as separate components and being axially interconnected, to move in unison, by an axial connection component, and, the interface of said first and second spools being connected to a predefined, external, hydraulic fluid leakage path.
