PRELIMINARY DESIGN OF WATER-JET PROPULSION SYSTEMS FOR 4000-TON CAPTURED AIR BUBBLE ( CAB ) SHIP
Preliminary estimates are made of weight and performance of four different arrangements of machinery for a water-jet propelled 4000-ton captured air bubble ship. The methods used for optimizing the V sub J/V sub O ratio and for calculating performance are outlined. All four machinery systems provide cruising speeds of 78 to 80 knots in smooth water using 150,000 horsepower, exclusive of the power required to supply cushion air. Weights of the complete machinery systems vary from 3.8 to 5.0 pounds per horsepower. ( Author )
