Abstract

PURPOSE: To reduce the water resistance and improve propulsion efficiency by generating bubbles from the ship's bottom, and by covering the ship's bottom with the bubbles.
CONSTITUTION: Streaks or membranes of bubbles shall be generated out of the submerged zone 2 of the progressing hull 1, and guided to cover the most part of the hull. Then, the hull is covered with the bubbles of much smaller viscosity factor than that of water, the resistance on the hull caused by its progression is reduced navigation speed can be increased in proportion to this effect.
