SOME RESEARCH ON SHIP MANEUVERING DEVICES

One method of obtaining high maneuverability at speeds between one and five knots is a rotating cylinder flap rudder which comprises a conventional rudder with a trailing edge flap and a cylinder fitted at the leading edge of the flap. For a high degree of maneuverability the main rudder would be inclined perhaps 20 degrees, the flap a further 70 degrees and the cylinder rotated. The full power of the engines would thus be deflected through 90 degrees and they could be kept full ahead without inducing any ahead way. It has been found from model experiments that this technique enables a vessel starting with any speed to lose way rapidly and to turn in such a tight circle that it virtually spins on its axis of rotation.
