INTEGRATED SHIP MACHINERY SYSTEMS WHICH RESULT IN SMALL, EFFICIENT DESTROYERS

The use of properly selected integrated ship machinery systems can sharply reduce the size, installed power, and fuel consumption of future Destroyers without reducing payload, speed, range, margins, or stability. One properly chosen subsystem opens the way to using a second superior subsystem, thus a third one, et cetra, forming a sort of beneficient chain reaction. The superior subsystems themselves provide highly leveraged effects on the displacement of the ship. Synergism of this entire chain can result in ships with markedly reduced initial and operating costs. The most essential elements of this system are: aircraft derivative gas turbines; compact, lightweight electric transmissions; large battery energy storage systems; and contrarotating propellers. Adoption of these systems permit secondary high-leverage subsystems to be used, including efficient ship service power from propulsion turbines and light-weight maintainable propulsion pods. These changes make total ship rearrangement possible, resulting in major decreases in turbine ducting, propulsion shafting, electric power distribution, and propulsion auxiliaries. Similar benefits in the auxiliary machinery system result from adoption of reverse-osmosis fresh water production, heat pumps for space heating, glass-reinforced plastic piping, controllable-speed, high-efficiency pump motors, et cetera.
