A Review of Practical Water-Jet Propulsion 720278

A decade's evolution and application of practical waterjet propulsion is described. Reasons for selecting types of pump elements are identified on the basis of efficiency and flexibility to suit the most commonly encountered engines and craft types. Preferred configurations for water inlets and control devices are described. Experience with propulsive efficiency, reliability, cost, boat and engine matching, maintenance, maneuverability, cavitation, and corrosion is discussed. Favorable performance in these areas compared with existing propeller systems is shown.
