Abstract
Apparatus for sequencing the release of a missile from its launch apparatus, the unlocking of the missile's warhead fuze pre-launch safety lock, and the ignition of the missile's rocket motor. A cylindrical block having a radial passageway is situated between the warhead and the rocket motor of a missile. An actuator piston having a hollow cylindrical core slides within the passageway. One end of the actuator piston projects from the passageway and is engaged with the launch apparatus to prevent movement of the missile relative to the launch apparatus prior to launch. A source of pressurized gas communicates with the hollow core of the actuator piston through an opening in the actuator piston's projecting end. A notch in the side of the actuator piston is engaged with the warhead fuze pre-launch safety lock. The introduction of the pressurized gas into the actuator piston drives it into the passageway and results in the withdrawal of the projecting end of the actuator piston from its engagement with the launch apparatus, while simultaneously forcing the engaged notch to unlock the warhead fuze pre-launch safety lock. The actuator piston continues to travel into the passageway until…
