    Abstract: A hydraulic charging and driving system (4), aircraft employing the same, and corresponding methods, for extending and retracting a hydraulic actuator (2), comprising: a motor assembly (22); and an accumulator assembly (20), the motor assembly (22) and the accumulator assembly (20) being hydraulically coupled to each other; wherein the motor assembly (22) is arranged to recharge the accumulator assembly (20) with hydraulic fluid at a relatively slow rate that is slower than the rate at which the accumulator assembly (20) is arranged to discharge when actuating the hydraulic actuator (2). The system may further comprise a selector valve (24). The accumulator assembly (20) may comprise an accumulator chamber (30), and a compression means (32) provided within the accumulator chamber (30). The motor assembly (22) may comprise a motor (42) arranged to vary a volume of a hydraulic charging chamber (38) of the motor assembly (22).
