Title: Sven-Gunnar Karlsson: Innovator in Water Jet Propulsion Systems
Introduction
Sven-Gunnar Karlsson is a notable inventor based in Kristinehamn, Sweden. He has made significant contributions to the field of water jet propulsion systems, holding a total of five patents. His innovative designs have the potential to enhance the efficiency and functionality of maritime vessels.
Latest Patents
Karlsson's latest patents include a method for a water jet propulsion system for ships. This system features a stator shell that can be mounted to the hull, equipped with a nozzle that has a cross-sectional outlet area. The impeller housing is attached to the stator shell and includes an upstream inlet. The impeller, which is rotatably mounted in the housing, receives water from the inlet and discharges it through the nozzle, creating a water jet upon rotation. The method also 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.
Another significant patent is a steering arrangement for ships propelled by water jet. This invention comprises a pivotal steering device connected to a vertical shaft, along with hydraulic cylinders for turning the steering device. The design ensures that all hydraulic cylinders are arranged within a sheltered space above the vertical shaft, allowing for easy maintenance from inside the ship.
