LIFT GENERATING STRUCTURE OF SHIP AND SHIP HAVING LIFT GENERATING STRUCTURE

Japanese Patent JP3486373

B2

PROBLEM TO BE SOLVED: To inhibit the increase in the hull resistance by forming a front water contact surface curved into the concave shape and having the downward gradient at a lower part, and forming a rear water separation surface adjacent to a rear end of the front water contact surface through a corner part, and kept in a non-water contact state in navigation.
SOLUTION: A float body 2 is provided with a lift generating part 5 consisting of a front water contact surface 3 and a rear water separation surface 4 in a state that it is downwardly projected, and the front water contact surface 3 and the rear water separation surface 4 are connected through a projecting part 5c in a bent state. The front water contact surface 3 is curved into the concave shape, and provided with the downward gradient. Whereby the big lift can be generated without increasing the resistance in navigation, and the high-speed navigation can be stably provided. By connecting the rear water separation surface 4 with the front water contact surface 3 through the projecting part 5c, the air can be easily guided to a rear part of the rear water separation surface 4, which prevents the generation of the negative pressure in accompany with the generation of the lift on the front water contact surface 3.
