Multiobjective Design Optimization of B-Screw Series Propellers Using Evolutionary Algorithms
Abstract:Methodical series are still widely used in the preliminary design of light- and moderate-duty marine propellers. If the above series enables standard screws to be designed by simple chart methods, they do not help the designer to deal with a complex design involving multiple and conflicting objectives. In this paper, a multiobjective optimization method of B-screw series propeller is introduced that makes use of an evolutionary algorithm maximizing both efficiency and thrust coefficient with a constraint determined by cavitation. The capabilities of the method are illustrated and discussed in detail. The results following the application of the method are given in the form of diagrams, which can be implemented on a common personal computer and used to derive optimal screw configurations in real time.
