Abstract
A launcher includes an impulse cylinder connected to a launch tube. An impulse piston, disposed within the impulse cylinder has a water side and an air side. The water side is in fluid communication with the launch tube. The air side is in fluid connection with a high pressure air source. A shaft connects a hydraulic cylinder is to the impulse cylinder. The shaft connects a hydraulic piston to the impulse piston. A control valve is connected to the hydraulic cylinder and controls movement of the hydraulic piston, which in turn controls movement of the impulse piston. Upon launch, the control valve allows movement of the hydraulic piston which allows movement of the impulse piston, providing water behind a projectile.
