抄録

An improvement of hull forms with less wave resistance is presented using Guilloton's transformation. The equivalent source distribution for a given conventional ship form is obtained in a mathematical flow field where the linear thin ship theory becomes applicable. Adding a small amount of source distribution, the optimization is carried out. The optimized total source is re-transformed to the real hull, that is, the modification of the given hull. The method is applied to the fore-body of a refined container ship and a very slightly modified hull is obtained. Two models, "the given hull" and "the modified hull by the present method" are resistance-tested and wave-analyzed. Results indicate that ; 1) the present method is efficient for improving conventional hull forms, and 2) the effectiveness of Guilloton's transformation is attributed mainly to the improvement of the linear free surface condition.
