Abstract

PURPOSE: To improve a propeller efficiency on the whole, by a method wherein a thrust is caused to be generated at a ring-shaped structure through the installation of the ring-shaped structure just forward of a front propeller.
CONSTITUTION: When a ship 1 starts to make headway with the rotation of propellers 4 and 5, a flow turbulence generated in the promixity of the stern is modified by means of a ring-shaped structure 3, and is caused to flow toward the propeller 4 in a manner to form in the ring-shaped structure 3 into a flow which has no mottle and is uniformlized. Meanwhile, a thrust is generated at the ring-shaped structure 3 itseft as well through the hydromechanical interference of the propeller 4 and the ring-shaped structure 3, and a propulsive factor can be substantially improved in combination with the thrust of the propeller 5.
