Abstract
A ballistic tolerant linear actuator incorporates a piston (16, 46, 76) and piston rod (38, 42 or 48, 50 or 90, 92) within a cylindrical housing (58, 60 or 81, 88) connected at each end (14, 22 or 42, 54 or 74, 82) to a source of fluid. A sleeve (18, 62 or 88) of a metal matrix or composite material which will break or puncture but which will not bend or petal on impact is incorporated as part of the barrel within which the piston is translated. The piston rod which extends through at least one end of the cylindrical housing is formed with an external sleeve of the metal matrix or composite material (38, 50 or 92) spaced from an internal load carrying metal rod (42, 48 or 96). A plurality of such actuators are connected together in a redundant arrangement such that when a projectile strikes an actuator, it may puncture the housing (58, 60 or 81), causing a loss of hydraulic fluid, it may puncture the sleeves (18, 62 or 88), but these sleeves do not deform in such a way as to prevent the piston (16, 46, 76) from travelling in the sleeve (18, 62 or 88) or the rod (38, 50 or 92) from passing through the end of the cylinder.
