MOTION ANALYSIS OF ASYMMETRIC SHEAR PLANE HEELING RUDDERS FOR WATERCRAFT
In the Heeling Rudder concept, for which visual and mathematical models are presented, one or more rudder blades are arranged on a shear plate to turn on a single axis. Unlike the conventional centreline spade rudder, the "Heeling Rudder" can not only cause a ship to change direction but can also cause it to roll in a selected direction at the same time. The heeling action is accomplished by the angle that the blade makes with the shear plate, i.e. the dihedral angle. "Heeling Rudders" can be designed to use conventional rudder stocks and steering power systems. Therefore, a one-for-one replacement of the conventional rudder is possible. The benefits to be obtained from Heeling Rudders compared with conventional rudders are: less parasitic drag; low-drag configuration: transverse force increase: structural weight reduction; improved control when backing; adaptable to computerised steering technology.
