Abstract
PURPOSE: To prevent the generation of a high stress caused by a composite bending and tortional stress of the blades by connecting the outer edge parts of the propeller blades and the propeller boss with auxiliaryblades of a wing-shaped cross section.
CONSTITUTION: The rear edges near the respective outer edges A of the propeller blades 11aW11e are connected to a propeller boss 3 by corresponding auxiliary blades 14aW14e. Each auxiliary blade has a cross section the same with that of a normal propeller blade. Thus application of a high stress to the rear edge of the blade is prevented, since the lift around the outer edges of the blades is produced by the auxiliary blades 14aW14e as well as by the propeller blades 11aW11e.
