Apparatus and Method for Designing a Specially Ported Torpedo Launching System to Damp a Seawater Piston.

Abstract

This patent application is for a low-noise, low-pressure torpedo launching system having specially designed ports connecting a water cylinder to an impulse tank and is a method for designing such ports. A specifically designed C-shaped water cylinder discharge ports is used 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.
