ABSTRACT:
The thrust of a Magnus propeller is made reversible by reversing the rotation of the Magnus cylinders independently of the direction of rotation of the propeller shaft. Reversible drives for the cylinders are provided that are mechanical, fluid or electric. Reversible motors for the propeller shaft are provided as an alternative reversing mechanism while the cylinders continue to rotate in the same direction. Separate motor drives are provided for the Magnus cylinders and the propeller shaft.
