5203 |a"A new propeller performance evaluation method has been developed for use in Concept Exploration Models (CEM) for conventional destroyer-sized ships. The method, based on the use of a Wageningen-B series propeller, is simple and convenient to implement, provides outputs of efficiency and propeller rotational speed, and can be used to simulate fixed-pitch or controllable-pitch propeller installations. The Wageningen-B propeller is shown to be the most suitable of four candidate propellers for current CEM applications. Used in conjunction with the large diameters now considered feasible, this propeller gives near-optimum efficiency and produces the conditions of propeller loading and rotational speed currently favoured for good acoustic performance"--Abstract, page ii.
