    • PROBLEM TO BE SOLVED: To provide a propeller jet flow generating device that effectively achieve an improvement of a thrust efficiency by preventing generation of cavitations by making a propeller wake distribution uniform, and an improvement of the thrust efficiency by reducing a swirl flow downstream of a propeller by forming an inverted flow upstream of the propeller. SOLUTION: A propeller jet flow generating device 100 includes a pump 5 serving as a sea water intake/eject means for taking sea water SW from an intake port 2 provided to a ship bottom 1 therein and ejecting the taken sea water SW toward the rear of a ship body from an ejection port 4 provided to a stern 3. The device generates a jet flow 7 toward a propeller 6 attached on a rearward part of the ship body relative to the ejection port 4. As the sea water intake/eject means, a cooling sea water intake means of a ship equipment 8 is used. In addition, at least one of an ejecting amount and an ejecting direction of the sea water SW being ejected from the ejection port 4 is changeable. In addition, the inverted flow is formed upstream of the propeller 6 by the generated jet flow 7. COPYRIGHT: (C)2011,JPO&INPIT

    • PURPOSE: To provide a sufficient rectifying effect even in ships having a narrow gap between the stern end and a screw propeller by providing recesses in which rotary cylinders are fitted at both broad sides of the stern hull in front of a screw propeller.
      CONSTITUTION: When a hull 1 bulges beneath the water surface 5, the flow speed of water flowing into a screw propeller 2 on sail of a ship is very much reduced at the center plane of the hull passing through the stern end 8 to produce the unevenness of flow. In view of this fact, recesses S are provided in both broad sides of the stern hull, and rotary cylinders 9 driven from the interior of the ship through vertical watertight bearings 14 are provided respectively in said recesses S. The rotary cylinder 9 is disposed projected rather from the surface 16 of the hull in relation to the radius 17 and rotatably driven in the direction of arrow 18 by a drive unit 15 in the ship 12. Thus, water flow flowing along the surface 16 of the hull to the screw propeller 2 is accelerated.

    • PURPOSE: To enhance the propelling efficiency of a ship, by fitting a ring-like structure to a hull in such a way that a space is defined between the rear end edge of the ring-like structure and a propeller, and as well by providing small type propellers in a stern bilge part front of this ring-like structure.
      CONSTITUTION: A ring-like structure 2 is attached to a hull 5 in such way that a space (d) is defined between the rear end edge of the ring-like structure 1 and a propeller 4, and the ring-like structure 1 is fitted in the hull 5, more than 20% of the length L of the upper section of a ring-like structure 1. Further, small-type propellers 8 are attached to both sides of the stern bilge part 5' of the hull 5 front of the ring-like structure 1. These small-type propellers 8 are rotationally controlled to apply outer-peripheral rotation to three-dimensional separation vortices. Accordingly, the ascending stream passing around the stern bilge part 5' is applied with outer peripheral rotation by the small-type propellers 8 so that the generation of three-diemensional separation vortices may be prevented. Thereby, the stream flowing in the ring-like structure 1 is rectified by the latter and thereafter is fed to the working surfaces of the propeller 4.
