    摘要： Disclosed herein is a propulsion apparatus for ships. The propulsion apparatus, which includes a front propeller and a rear propeller to rotate in opposite directions and provides propulsion power to propel a hull of a ship, includes a power unit to supply power to rotate the rear propeller, a main shaft to transfer the power supplied from the power unit to the rear propeller, a hollow shaft extending in a longitudinal direction of the main shaft to allow the main shaft to pass therethrough and coupled to the front propeller, a drive motor including a rotor coupled to an outer circumferential surface of the hollow shaft and a stator supported by the hull, the drive motor rotating the hollow shaft in a direction opposite to a direction of rotation of the main shaft, and an electricity supply unit to supply electricity to the drive motor.

    摘要： A propulsion apparatus for a vessel includes a main screw and a push type POD propeller which is provided rearward of the main screw. Furthermore, a plurality of grooves which extend along flow directions of a hub vortex generated by the main screw are provided on a front end portion of a casing of the POD propeller. According to this propulsion apparatus for a vessel, the hub vortex generated by the main screw rearward of the main screw is weakened by diffusing the hub vortex along the grooves, and therefore the propulsion efficiency of the propulsion apparatus for a vessel is improved.
