| Abstract: | This paper introduced the problem of the propeller transverse force in its reverse stat.Through the analysis of these states,this paper provided a new theory method far the calculation of propeller transverse force.Simulating with the way of transverse force of discharge current,which acts on the rudder,the formula of its action on the astern is deduced and then the coefficient of Transverse Force of Propeller Oblique Flow is corrected.Theory in this paper,by using different ship models as simulation objects to research,finally,is proved by the experimentation of a real vessel.The illustrative examples show the effectiveness of the proposed method. |
