The invention discloses a structured set of electro-hydraulic pilot servo valves to operate an actuator arm to raise and lower an ammunition cradle. The servo valve structure and operational logic provides redundancy and reduces probability of failure. If one of the valves malfunctions, the remaining other two valves vote to carry more flow to compensate for the lost capacity thereby continuously maintaining system performance at pre-failure or near full capacity levels.

Majority voting 3-stage servo valve system

This invention relates to a material handling system. More particularly, the invention pertains to the method and apparatus for automatically loading a two-piece ammunition into a gun tube. A continuous rammer mechanism having a plurality of strategically spaced pawls is structured to accelerate the two-piece ammunition into the gun tube. The system compensates for different angles of gun trajectory by adjusting the speed and output of a drive motor to thereby provide a consistent ramming acceleration of the ammunition.

Two-piece ammunition flick ram

A material hand-off mechanism and process which utilizes a pendulating arm to deliver material to and or accept it from a load station which cooperatively engages the arm. The load station and the arm provide interceptive, interactive and linkless conveyance capable of independent and parallel operations to enhance efficiency and availability of the system. Particularly, the mechanism is suited to transfer ammunition from a storage station into a gun tube. The ammunition is rammed into the gun breech using a flick ram mechanism, which operates in cooperation with the arm, and enables a sure ram of ammunition comprising different modules.
