• 要約等: Developing full form ship with maximum efficiency self-propulsion factors (t: Thrust deduction factor, ω<SUB>s</SUB>: Wake fraction, η<SUB>r</SUB>: Relative rotative efficiency) is as important as developing one with light resistance. Recently, some optimization methods using CFD have been developed. However these methods need significant computation time. In the practical design stage, design time is never enough. So we aim to develop an optimization method requiring less time.<BR>In this paper, an optimization method for a full form ship with minimum thrust deduction factor has been developed. The object of our optimization method is to get a hull form with minimum thrust deduction factor for shorter computation time. Our optimization method consists of nonlinear programming (SQP: Sequential Quadratic Programming), deformation method for hull form, and prediction method based on potential theory for thrust deduction factor. The results of this optimization are shown in this paper. We verified the results through comparing with the self-propulsion test in NKK TSU SHIP MODEL BASIN.
