Abstract:

The invention is low-noise, low-pressure torpedo launching system having specially designed ports connecting a water cylinder to an impulse tank and to a method for designing such ports. The invention uses specially designed C-shaped water cylinder discharge ports to provide a continuous and minimized pressure gradient as the ports are closed by the water piston. The resulting controlled deceleration of the water piston reduces operational noise,-reduces mechanical stresses and eliminates the need for auxiliary dashpot components.
