KaMeWa Reports Lively Interest In Water Jet Propulsion Units Maritime Reporter, Oct 15, 1984 #9 ; After a moderate start at the end of the 1970s, KaMeWa AB of Sweden is now experiencing a spreading interest in the water jet (WJ) for vessel propulsion.
MJP CSU, Compact Steering Unit, is a well-proven mixed-flow all duplex stainless steel waterjet. The vessel is installed with 4 sets of diesel-engine driven KAMEWA water-jet propulsion system capable of making a maximum cruising speed of 42 knots. At constant rpm the waterjets absorb approximately the same power regardless of the vessel’s speed, so the engine cannot be overloaded, giving it a longer lifetime. The Kamewa water jet is equipped with an integrated reversing mechanism attached to the steering unit.
In this thesis a conceptual design for this motor is presented, in which bearings and seals have been chosen from standard components as well as the bolts and other components, and all the housing has been designed. Propeller geometry design and off-design performance for the propeller variants were characterized using the Propellei Lifting Line computer program developed at MIT. Achieving a reversing thrust is done the same way as for achieving steering, namely by manipulating the direction of the jet stream. A single jet can power a two‐ton planing vessel, and suitable configurations are also available for displacement and semi‐displacement hulls. Such drives pump water at great velocity through a nozzle pointing astern, propelling the boat forward.
