    摘要: Disclosed is an asymmetric preswirl stator (1) of a ship.
    The asymmetric preswirl stator (1), which is installed in front of a propeller (2) of the stern of a low-speed full ship for improving a speed capacity of the ship, has various asymmetric structures in consideration of wake current characteristics of the hull of the ship and a rotational direction of the propeller, thereby having an improvement in efficiency and a reduction in weight and making the load distribution on the propeller uniform, and thus improving the efficiency and the cavitation property of the propeller
