  • Apparatus and method for decreasing drag force by controlling turbulent flow on hull surface of ship
    Patent number: 6659030
    Abstract: The present invention relates to an apparatus and method for decreasing drag force by controlling turbulent flow in a hull surface of a ship. The method and apparatus according to the present invention are directed to sucking and ejecting the fluid flowing along a hull surface of a ship, varying the turbulent field of the turbulent flow, controlling the ejection angle with respect to the hull surface and decreasing the friction resistance by providing a pipe housing which is installed in a hull surface of a ship and includes a plurality of slits, a flexible air pipe which is installed in the interior of the pipe housing and performs contracting and expanding operation based on air pumping operation, and a pump which is installed in the hull for contracting and expanding the air pipe and providing air to the air pipe.
