ABSTRACT:
A mechanical actuation system for secondary centerbody nozzle actuation commonly associated with a dual area solid rocket nozzle configuration that utilizes a rotating ring in combination with at least one piston connected to pins that are affixed to the movable centerbody. The ends of the pins adjacent the rotating ring are misaligned with holes in the rotating ring such that the ring lock prevents the centerbody from moving to a closed or blocking position until such time as the ring lock is rotated by ring actuation means to align the holes with the pins. The pins then simultaneously slide through the holes moving the centerbody to the closed position.
