| 内容記述 | The number of ships equipped a shilling rudder has increased recently. It is easy comparatively to estimate a performance of a rudder that has a section as a normal wing section. But it is not easy to estimate a performance of a shilling rudder, theoretically with conventional methods, had inverse-wedge-shape. Therefore we have started from checking a situation of a surrounding flow of a rudder. And models of shilling rudder and of normal rudder with rectangle were made. Experiments were carried out in the circulating water tank of Kagoshima University. Experiment on visualization of 2-dimensional flow fields in mid-span section of each rudder was done by depth tuft method. Furthermore the lift and the drag acting on the rudder and moment of the rudder shaft were measured. The influences that the rudder tail wedge angle of the shilling rudder effected these forces and moment were examined. As a result the following understood. When a rudder angle is 0, especially one of a shilling rudder, a flow of behind rudder was unstable in a flow immediately, after trailing edge. To calculate the forces acting on a shilling rudder theoretically, especially a situation of a flow around the tail part of a rudder needs to be grasped. We knew to be necessary to make visibility of the position where parted more from a relation. It is able to say that a shilling rudder is excellent in turning even from a normal rudder obviously. A value of drag of a shilling rudder is always larger than a normal redder. Wedge angle of the shilling rudder tail might make a turning performance conversely worse when the angle is greater than 20°. As one of methods to calculate numerically the performance of a shilling rudder, we conceive that to add an influence of wedge angle α to one after determining the performance of a shilling rudder of wedge angle α=0, first. | |||||
