  • MARINE VEHICLE HAVING PRE-SWIRL GENERATOR FOR GENERATING PRE-SWIRL FLOW
    Publication number: 20100258045
    Abstract: A marine vehicle includes a hull, a rudder, a propeller, a swirl generator mounting region provided on an outer surface of the hull and located on a port side or a starboard side where a rotation direction of the propeller is downward, and a pre-swirl generator having a swirl creating wedge disposed in the swirl generator mounting region. The swirl generator mounting region is disposed in front of a central axis of the rudder and behind a vertical line spaced from the central axis by a distance that is 0.2 times the length of the vehicle. The swirl creating wedge is inclined with respect to a waterline by an angle (?1) of 13°-45°. The pre-swirl generator can produce a flow guiding effect that enhances propulsive efficiency of the marine vehicle.
