Abstract
In a dual area nozzle automatic mechanical actuation system for a boost-sustain solid propellant rocket motor, a pressure differential is created on the opposite sides of a ball-catch retaining ring when a fast-burning portion of the solid-propellant grain is spent and a slow-burning portion is ignited that allows the blow-out load on the smaller throat orifice of a mechanically restrained movable nozzle section to move the movable nozzle section to seat the smaller throat orifice against the larger throat orifice of a fixed nozzle section.
