Latest Patents

Lars holds a patent for a method and system for a water jet propulsion system for a ship. This invention includes a stator shell designed to be mounted to the hull of the ship, featuring a nozzle that ends in an outlet with a specific cross-sectional area. The system also comprises an impeller housing attached to the stator shell, which has an upstream inlet. An impeller is rotatably mounted within the housing, allowing it to receive water from the inlet and discharge it through the nozzle, thereby creating a water jet when the impeller rotates. The method involves reducing the outlet area by partially closing the nozzle during the startup phase of the propulsion system. Additionally, a backflow hindering arrangement is included to prevent air from entering the impeller housing via the nozzle.
