Abstract
A component for use in a ram air turbine actuator includes a lock bolt extending along a centerline with the lock bolt being axially movable between a stowed position and a deployed position and a plurality of rollers that are radially outward from the centerline and guided by the lock bolt. The component also includes a slider radially between at least a portion of the lock bolt and a piston rod with the slider being axially movable between a stop position and the deployed position and up-lock wedges supported by the piston rod. The actuator becomes locked in the stowed position when the lock bolt and slider move axially within the piston rod and a cylinder to position the rollers to push the up-lock wedges radially outward into an aperture and prevent the lock bolt, slider, and cylinder from axial movement.
