Abstract
An actuator (10) tolerant of ballistic damage thereto includes a piston (25) longitudinally reciprocable within a cylinder (15) and connected to a rod (30), the piston comprising a plurality of longitudinally stiff, circumferentially spaced ribs (35) joined by a bulkhead (40) which transfers hydraulic loading to the ribs and readily ruptures in response to impact with an obstruction (45) in the cylinder wall due to for example, ballistic damage to the actuator. The bulkhead carries a sealing ring (60) for sealing leakage around the piston and may be formed integrally with the ribs or separately therefrom and attached thereto as an end cap to the piston. Analogous structure may be employed in a gland (20) for the actuator to accommodate ballistic damage to the rod.
