摘要： Disclosed herein is a ducted pre-swirl stator assembly. The ducted pre-swirl stator assembly includes a pre-swirl stator, a cylindrical duct and a support. The pre-swirl stator is provided on a stern boss of a hull and has at least one blade extending in a radial direction based on the center axis of a screw. The cylindrical duct is coupled to the outer end of the blade of the pre-swirl stator. The support fastens the duct to the hull. The center axis of the duct is eccentric upwards and rightwards from the center axis of the screw with respect to the direction indicated from the stern side to the bow side. In the present invention, the pre-swirl stator and the duct are configured and arranged such that the optimal coupling therebetween is realized, thus maximizing the propulsion performance of the screw.
