Abstract : This patent discloses a hydraulic actuator having redundant cylinder assemblies, each assembly being of lightweight and economical construction in having a relatively thin tubular wall reinforced to withstand hydraulic pressure by a layer of resin reinforced filament, the thickness and the material of the wall being such that petals formed from the wall by projectile penetration are sheared by engagement with a piston of the assembly as this piston is moved, together with an actual element, by the piston of the other assembly. Ammunition damage tolerance; Patents. (edc)
