Then the propeller receives complicated and mutual interference with a hull and a rudder. We usually divide the ship into three parts i.e. the hull, the propeller and also the rudder, when we consider the problem of the ship propulsive performance. The propeller occupies an important part of ship propulsion in the sense that it affects the hull and the rudder largely. Moreover a propeller operates in such a non-uniform flow, and then we require a numerical method that the calculation of the propeller performance is easy and the computing time is short. And such a computation method should be able to estimate well the forces and the moments acting on the propeller and also the velocity field around it finely. For this purpose, there are some computation methods based on "equivalent infinitely-bladed propeller". However, the value of a section drag coefficient of a propeller blade was taken generally too large in these methods. Therefore these methods are inappropriate when the scale effect or the characteristics of an actual ship propeller are estimated. In this paper, in order to take into account the viscous, effect, the authors attempt to improve the numerical method based on the Ueda-Yamazaki's theory of "equivalent infinitely-bladed propeller". And then results are compared with the experimental values. An application to an actual ship propeller is also examined.}, pages = {99--112}, title = {実船プロペラ性能の近似計算法について : 相当無限翼数プロペラ計算法の改良}, volume = {39}, year = {} }
