Underwater Rapid-Fire Ram Pump.
Abstract
This invention relates generally to underwater launching systems and, more particularly, to an underwater launching system that uses a ram pump to achieve rapid-fire launching. A further object is to provide a dual barrel underwater launcher that is pressure balanced with submergence pressure. Thus, an apparatus is provided that is capable of a rapid firing sequence for an underwater dual barrel launcher. An air cylinder assembly drives a water piston housed in a water cylinder in either of two opposing piston stroke directions. The water cylinder is continually supplied and balanced with sea pressure. A piston stroke in a first direction pressurizes impulse water in the water cylinder that is then supplied to a first launch tube of the dual barrel launcher. A piston stroke in an opposing second direction again pressurizes impulse water in the water cylinder that is then supplied to a second launch tube. Thus, each opposing piston stroke is a power stroke.
