特徴とする船舶の推進性能向上装置。 A wheel is provided at the rear of the screw propeller that can freely rotate around the same axis as the screw propeller.The wheel is composed of multiple turbine blades and a thrust blade at the tip of the screw propeller, and is rotated by the turbine blade. In a ship propulsion performance improvement device that receives force and generates thrust in the thrust blade section, a fynboss surrounding the bossing is installed in front of the screw propeller.
A plurality of fins are provided to protrude radially, and the length of the fins from the propeller axis to the tip is equal to or greater than the thrust blade, and the water flows in the opposite direction to the forward rotation direction of the propeller. A vessel propulsion performance improving device characterized by being twisted so that it can be bent.
