Abstract
A drive system for operating a ram air turbine (RAT) re-stow pump assembly includes a pump piston and a cylinder in which the pump piston moves axially in a reciprocating linear motion when driven by the drive system. The drive system includes a rotary drive shaft and a linear link member having a first end connected to the rotary drive shaft and a second end arranged to be connected, in use, to the pump piston of the RAT re-stow pump. Rotation of the drive shaft is translated to reciprocal linear motion of the piston when connected to the link member, via the link member. The drive shaft is provided with an attachment fitting configured to attach to a rotary power tool, in use, to drive rotation of the drive shaft.
