FORCE CALCULATION OF A RECTANGULAR PLATE MOVING AHEAD AND YAWING IN DEEP WATER. (THE CASE OF A MOVING VORTEX)

In the previous paper, the author estimated the stability derivatives of a ship manoeuvring in deep water. The previous paper was calculated by means of Bollay's method that at the ends of the span each bound vortex was assumed to leave as a trailing vortex at some angle to the wing. However, the interaction of each vortex which was produced as the wing moves was not considered. But, in actual condition, it can be supposed that these vortices interact with each other and move as the time proceeds. Therefore, the present calculation considers a moving vortex to find out the interaction of vortices in estimation of the stability derivatives of ship manoeuvring. Compared with the results of each calculation, it can be determined that a noticeable difference between the present calculated results and the previous one is not recognized.
