High power density propulsion/power system for underwater applications

Abstract

A unique arrangement of components comprising an open Rankine cycle power system for under water application is provided. The arrangement features a high energy density steam generator, a turbine, pumps and other apparatus to provide and control the flow of a seawater working fluid and the use of a mixing condenser to condense the spent steam. The mixing condenser uses droplets of seawater to condense the steam exhausted from the turbine. Alternatively, the steam may be introduced into a pool of water in the mixing condenser by means of a bubble device. The mixing condenser also provides a preheated feedwater supply for the boiler. This system facilitates the packaging of power sources an order of magnitude more powerful than current sources. Moreover, this system can be installed in current vehicles.
