Abstract

PURPOSE: To increase propulsive force of a blade and prevent occurrence of its cavitation, by providing a small blade generating a lift in the point end part of the blade.
CONSTITUTION: When a blade 12 of a propeller 11 rotates in a direction C, a lift L is generated to obtain thrust T and rotating torque Q as a component of the life. Then for totary speed N of the blade 12, a flow of speed U is acted upon the point end part of the blade 12, and a flow U1 having said flow speed U moves around from the front side to the rear side of the blade 12, to act upon a small blade 13 with a certain attack angle. In this way, lift l crossing at a right angle with the flow U1 is generated in the small blade 13 to obtain its components, thrust (t) and rotating torque (q), reversely operated to the rotating torque Q in the blade 12, in the blade 13. Accordingly, proper thrust T in the blade 12 can be increased by the thrust (t), further the rotating torque Q can be decreased by the rotating torque (q).
