Waterjet Propulsion for High Speed Jets 740281

Waterjet propulsion and its optimization for modern water crafts were considered and some comparisons were made between waterjets and propellers. The waterjet optimization process presented includes considerations of inlet drag, weight of the propulsor, and the effect of the head and flow rate design parameters of the waterjet on the range of the craft. The waterjet/propeller comparison showed that the waterjet is the preferred propulsor in applications of high and intermediate speed, applications requiring high maneuverability, and applications requiring shallow draft and immunity to water-borne debris.
