COMPUTER AIDED PROPELLER PRELIMINARY DESIGN, USING THE B-SERIES
This study deals with the preliminary design of the propeller using the B-screw series. A critical analysis of the original data published by NSMB showed the need of a correction for laminar flow effects. A correction method has been implemented and the corrected results showed excellent agreement with experimental data. The optimization problem, including a machine model, is stated in mathematical terms using the B-series. The formulation permits a statistical optimization of the propeller for a variety of weather or load conditions to be encountered. This new formulation of the propeller-hull-machine-wake system defines a more meaningful optimization criterion, such as minimizing fuel consumption. Four examples are worked out to demonstrate the new method. In one of the examples, the selection of the propeller for a containership operating in a specified route is worked out in detail.
