Abstract
PURPOSE: To increase the contact surface area with ice and heighten the ice breaking capacity, by makihg the bow tip cylindrical and setting the bow angle at 15W 25° and the side angle at 45W65°.
CONSTITUTION: The bow tip is made cylindrical with a radius r equal to 2W5 % of the maximum width of the ship body. The bow angle α is set at 15W25° and the side angle β is set at 45W65°. Thereby, the contact surface area with ice is increased, the compressive break of the ice on the contact surface is avoided, the resistance at the ice breaking is decreased, and the ice breaking capacity by bending is heightened. Since the bow is round, the resistance of water at ordinary voyaging is decreased.
