GUIDED MISSILE CONTROL ACTUATOR UNIT Russian patent published in 1997 - IPC

FIELD: defence equipment, in particular, guided missile control actuator units. SUBSTANCE: when the missile controls are in the folded position, air is not supplied to the inlet of actuators 1. Base 4 is installed in the control actuator unit, actuators 1 and cylindrical tube 9 are fastened to the base. Formed in the front part of tube 9 is a cylindrical part of smaller diameter with front wall 11 and radial holes 12. Piston 15 of controls unfolding mechanism 13 has two steps, the smaller step being in the front part, which has front wall 18 and radial holes 19. In the initial position before actuation of the controls unfolding mechanism, before actuation of the come to the initial position and get fixed by the lock mechanism, the smaller pipe step enters the smaller piston step. The radial holes in the pipe are closed. It prevents air supply to the actuator spaces up to the moment of unfolding of the controls. EFFECT: improved design. 2 dwg
