• The Purpose of this paper is to report and review how the author applied a high-speed electronic digital computer to the calculation of ship propulsive performance, as a part of the network of the application to ship calculation and initial design problems, which was conducted by Mr. A. Yamagata and Mr. N. Akatsu, a summary of which was presented at the Spring 1964 meeting of Zosen Kyokai.The paper deals with the following calculations : -1. EHP estimation using the Design Charts of Series 60 connected with the correction factor "C_<RD>" to an actual ship and Schoenherr's frictional formula, 2. Initial propeller design using the modified AU type propeller chart, 3. Power and revolution estimation calculated with the EHP, self-propulsion factors and the characteristic curve of the propeller designed, and4. Speed trial results analysis in order to obtain ship-model correlation factors.N.B. As for the application of a computer to the design of preliminary ship-lines and the correction of speed trial results against wind and current, the author has already reported in the Journal of Zosen Kyokai, No. 114,1963 (in English) and the Monthyl Journal of Zosen Kyokai, No. 416 (in Japanese) respectively.
