Device for reducing frictional resistance of ship body |
摘要 |
A ship-body frictional resistance reducing device for reducing frictional resistance of a sailing ship body by forming an air bubble curtain on a ship's bottom by generating air bubbles includes an air chamber provided on the ship's bottom inside the ship including an air supply port formed thereon, a plurality of air ejection holes formed in an array on the ship's bottom that serves as a bottom of the air chamber, and a diffusion plate provided inside the air chamber intervening between the air supply port and the air ejection holes. The diffusion plate is formed in a manner that it includes at least a supply-port facing area covering the air supply port and a pair of ejection-hole facing areas covering air ejection holes located at both edges of the air ejection holes in an arrangement direction. |
