OPTIMIZATION OF WATERJET PROPULSION SYSTEMS FOR SURFACE EFFECT SHIPS

Water-jet propulsion systems using flush inlets suitable for use on surface effect ships are studied. Equations are developed and incorporated into a computer program which optimizes the system on a least total weight basis. Resistance, displacement, range, speed and other data are used to calculate total propulsion system weight for a number of jet velocity ratios. The system utilizes marine gas turbine engines coupled to multi-stage axial-flow pumps. Variable area flush inlets and constant area nozzles are used. Results for a 2000 ton vessel are presented.
