Feasibility Study of Water-Jet Propulsion Systems for a 500-Ton Hydrofoil Ship

摘要

The results are considered to demonstrate that water-jet propulsion of high-speed hydrofoil ships is feasible and that the performance goals set by the Bureau of Ships are attainable. Considerable development work aimed toward the reduction of machinery weight appears necessary if total weight of fuel and machinery is to be held within the specified 250-ton limit. This requirement, in combination with that for 500-mile endurance at full power, is quite stringent, since fuel weight alone is then automatically fixed at 172 tons. The remainder, after deducting another 32 tons for prime movers, is only 46 tons, or less than one lb per horsepower for pumps, reduction gears, and accessories. (Author)
