PROPELLER, PROPELLER PROPULSION SYSTEM AND VESSEL COMPRISING PROPULSION SYSTEM

摘要

The invention refers to a propeller comprising a base (2, 15) and a plurality of blades (1, 14) extending from said base in an upstream tilted manner, i.e. in the direction corresponding to the forward motion direction (D1) of the craft. The blades extend in a direction forming an acute angle alpha with the forward motion direction, 10 DEG ≤ alpha ≤ 80 DEG . The invention also refers to a propulsion system including the propeller, as well as to a craft including the propulsion system.
