Abstract

See full text

A marine propeller is disclosed having two blades. The shape of the propeller blades remains constant through the radial position of the propeller blades. The blade length of the propeller blades changes as a function of the radial position of the propeller blade. The twist angle of each blade starts at approximately 63 degrees at the propeller hub (proximal end) and decreases to about 15 degrees at the blade tip (distal end).
