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 1 by forming an air bubble curtain on a ship's bottom 5 by generating air bubbles includes an air chamber 22 provided on the ship's bottom 5 inside the ship 1 including an air supply port 28 formed thereon, a plurality of air ejection holes 15 formed in an array on the ship's bottom 5 that serves as a bottom of the air chamber 22, and a diffusion plate 35 provided inside the air chamber 2 intervening between the air supply port 28 and the air ejection holes 15. The diffusion plate 35 is formed in a manner that it includes at least a supply-port facing area covering the air supply port 28 and a pair of ejection-hole facing areas covering air ejection holes 15 located at both edges of the air ejection holes 15 in an arrangement direction.
