摘要： An air lubrication system of an outer installation type has good efficiency. An air recovering device includes a recovery side chamber provided on a bottom of a ship on a stern side from an air ejecting device which supplies air bubbles to the ship bottom. The recovery side chamber includes air intake holes formed in a portion of the recovery side chamber opposite to the ship bottom through a gap. The air recovering device also includes a recovering section recovering air inside a recovery side chamber. The air bubbles acquired from the air intake holes are accumulated inside the recovery side chamber to generate pushing pressure so that air can be smoothly recovered from the recovering section.

摘要： A gas room is arranged in a hull to cross a longitudinal frame and extend in a width direction. A scattering member is arranged in the gas room to cross the longitudinal frame and extend in the width direction. Air blown into the gas room from an air supply pipe hits the scattering member to scatter in the width direction, and is blown from an air blowing hole formed in a bottom of the gas room into water. Because the gas room crosses the longitudinal frame and extends in the width direction, an air bubble flow with a wide width forms in the width direction by the single gas room. Therefore, the number of gas rooms for air bubble flow which covers the whole width of a ship bottom is reduced, and the number of air supply pipes which are provided to every gas room is reduced.

摘要： A ship air lubrication system of an external installation type with good efficiency is desired to be provided. An air ejecting unit includes an ejecting side chamber installed in a ship bottom of a ship and having air ejecting holes formed in a surface opposite to the ship bottom on a lower side; and a supply section which supplies air into an inner space of the ejecting side chamber. When the air in the ejecting side chamber is ejected from the air ejecting holes, the air is sheared by an external water stream, and small air bubbles are supplied to the ship bottom.

Air blown into the gas room from an air supply pipe hits the scattering member to scatter into the width direction, and is blown from an air blowing hole formed in a bottom of the gas room into water. Because the gas room crosses the longitudinal frame and extends into the width direction, an air bubble flow with a wide width can be formed into the width direction by the single gas room.

摘要： In 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 from a plurality of air ejection holes formed on the ship's bottom 5, the air ejection holes are arranged in a ship width direction to constitute an air-ejection hole group, and a plurality of air ejection holes groups of the same type as the air-ejection hole group is formed on the ship's bottom 5. The air-ejection hole groups include at least a center air-ejection hole group 30a formed at the center of the ship width direction at a bow side and a pair of side air-ejection hole groups 30b and 30b formed at a stern side from the center air-ejection hole group 30a at both sides of the center air-ejection hole group 30a in the ship width direction. A length of the center air-ejection hole group 30a in the ship width direction is formed to be longer than a length of the side air-ejection hole group 30b in the ship width direction.
