9-2 肥大船型における船体中央平行部長さの影響  [in Japanese] 9-2 Effect of Parallel Part Length on Propulsive Performance of Full Hull Form  [in Japanese]

In order to clarify the effect of the parallel body length on the resistance and self-propulsion factors of full hull forms, a methodical model test was carried out at SRC. This investigation was performed in cooperation with Nippon Kokan K.K., Ishikawajima-Harima Heavy Industries Co., Ltd., Hitachi Shipbuilding & Engineering Co., Ltd., Kawasaki Heavy Industries Ltd., Mitsui Engineering & Shipbuilding Co., Ltd., Sumitomo Heavy Industries, Ltd. and Sasebo Heavy Industries Co., Ltd. From the results of this systematic series test it was found that the longer parallel body gave a higher r_R in the higher speed range and a lower r_R in the lower speed range, and that the longer parallel body shows larger t and smaller w_T.
