Abstract
A method and apparatus for controlling the runout and initial recoil velocity of an artillery piece is disclosed in which variables of barrel elevation and the impulse delivered by a round of ammunition are hydraulically sensed as pressures trapped in actuators which control the flow of fluid to the recoil cylinders of the artillery piece. The system provides for a predetermined constant deceleration of the recoiling barrel assembly regardless of the type or power of the round utilized. When a constant predetermined deceleration is provided, the recoil velocity is uniquely determined and an automatic system is provided for assuring that the loading of the artillery piece always takes place at the same instant of time and that the barrel assembly will have decelerated sufficiently to prevent damage to the snubbing apparatus carried by the artillery piece.
