BLADE FOR PROPELLER OF SHIP

摘要

PURPOSE: A blade for a propeller of a ship is provided to arrange plural ribs on a bus of the blade of the propeller for being parallel and for freely projecting the ribs from the end unit edge of the propeller toward the outer side of the radius direction for increasing a precise efficient gain with a relatively low manufacturing cost. CONSTITUTION: A blade(2) for a propeller is formed by:an instrument for decreasing a turbulent air being generated in an outer circumferential area; plural ribs(R1 ¯ R4) being arranged for being extended to a bus(1) of the blade of the propeller in parallel while having an interval for forming the decreasing instrument; and the ribs being formed by being freely projected from the end unit edge of the blade of the propeller toward the outer side of the radius direction. Therefore, a precise efficient gain is obtained by using a low cost.
