Latest Patents
Aartojarvi 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 to receive water from the inlet and discharge it through the nozzle, creating a water jet upon rotation. The method involves reducing the outlet area by partly closing the nozzle during the startup phase, with a backflow hindering arrangement to prevent air from entering the impeller housing via the nozzle.
