Abstract
PURPOSE: To attempt improvement of efficiency of a propeller and prevent generation of cavitation, by fixing blade tip plates on the tip of the propeller blades.
CONSTITUTION: Blades of propeller 7 are bent of their tips or blade tip plates 6 are provided in parallel to the thrust shaft core or in an angle close to it. Thus, even if a nozzle is not fixed to the propeller as before, tip eddies are diffused, inductive resistance of the propeller is decreased, efficiency can be increased, and generation of cavitation can be also prevented simultaneously.
