Abstract
An asymmetric propulsion mechanism capable of providing both axial thrust as well as lateral maneuverability from a single axis of rotation is described. The mechanism may be used on aquatic vehicles to minimize cost and maximize reliability and endurance. The mechanism comprises one or more propeller blades disposed asymmetrically around a rotating hub under the guidance of a control system including a motor capable of driving the propeller at various radial speeds throughout the course of a single revolution.
