Overview: Traditional marine thrusters include two or more symmetrically distributed blades, built into or mounted to a marine craft. Aquatic vehicles generally employ one or more thrusters for propulsion and one or more actuators for maneuverability and propulsion. There is a demand for a low cost marine thruster and one that simplifies propulsion, maneuverability, and manufacturing to a single device would decrease associated costs, maintenance, and potential failure modes.
Technology: The Asymmetric Thruster is capable of both axial thrust and lateral maneuverability from a single axis of rotation. It’s operated under the guidance of a control system capable of sensing the radial position of at least one of the blades, and capable of executing various radial blade speeds throughout the course of a single revolution as a means to maneuver the vehicle.
