DUCT FOR SHIP AND SHIP INCLUDING THE SAME

摘要

PURPOSE: A duct and a ship with the same are provided to generate not resistance but thrust from flow flowing into a lower body of the duct because the lower body of the duct has an airfoil cross section. CONSTITUTION: A duct for a ship comprises an upper body(11) and a lower body(13). The upper body has an airfoil cross section. In the airfoil cross section, a pressure surface faces outside and a suction surface faces inside. The lower body has the airfoil cross section. In the airfoil cross section, a pressure surface faces inside and a suction surface faces outside.
