れを押し拡げて推進器の作動面内に供給するようにした
船舶が知られている。In general, it is known that as a ship's hull becomes larger, the flow of water near the stern becomes turbulent, making the ford area uneven, and as a result, the horsepower required for propulsion increases, as well as increasing vibration and noise. .ゞ- In order to improve this drawback, a ship is known to have a ring-shaped structure installed at the stern of the ship, which collects the slow flow flowing on the side of the ship, spreads it, and supplies it to the operating plane of the propeller. It is being
このリング状構造物を船尾部に設けることは顕著な効果
があり、推進に要する動力は１０チ程度減少し、これと
同時に振動や騒音も減少することが確認されている。It has been confirmed that providing this ring-shaped structure at the stern has a remarkable effect, reducing the power required for propulsion by about 10 inches, and at the same time reducing vibration and noise.

。In particular, the support member 1 that supports the ring-shaped structure 14 from below
1 consists of a cover plate 5 and reinforcing plates 6 and 7. First, the reinforcing plate 6 is connected to a ring-shaped structure 14 as shown in FIG.
The sole piece 16 is placed directly under the second ring web 17 and fixed to the ring-shaped structure 14 and the sole piece 16 by welding. Next, the reinforcing plate 7 is placed directly under the third ring web 18, as shown in FIG. 4, and is fixed to the ring-shaped structure 14 and sole piece 13 by welding. Next, the cover plate 5 has a U-shape, is arranged so that its rear end is directly under the fourth ring web 19, and is fixed to the ring-shaped structure 14 and the sole piece 13 by welding.
