Abstract
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.

An actuator arrangement comprising 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.
An electrical thrust reverser system comprising an extendable actuator driven by an electric motor, the actuator including a rotatable screw shaft and a translatable nut, the actuator being provided with limit stops to limit the permitted range of extension of the actuator, at least one of the limit stops being compliant, wherein the compliant stop is provided by locating a torsion bar within the screw shaft, a stop member being associated with the torsion bar, the stop member projecting through a slot formed in the shaft and engageable by a stop associated with the nut translatable along the screw shaft.
