    • 专利摘要:
    A vessel equipped with a single screw comprising a hull being symmetrical with regard to the hull cener line and a propeller shaft (3) being positioned eccentrically from the hull center line (2). The propeller shaft is positioned at a ratio (d/D) of 5 to 25%, where d represents a distance between the propeller shaft and the hull center line and D represents a diameter of the propeller.

    专利说明:

    This invention relates to shipbuilding, in particular to the positioning of a propeller on a ship.
    The purpose of the invention is to increase the pro ductive qualities.
    Figure 1 shows the vessel, a general view of the measles; tg, 2 - flow diagram in the form of velocity vectors at the inlet B, the plane of rotation of the propeller; Fig, 3 - installation of propellers. on the hull of the vessel; 4, the same embodiment.
    The vessel contains the hull 1, tach filled symmetrically with respect to the median plane 2 of the vessel of the form. The ship has a propeller 3 mounted on the shaft 4. The aft end of the shaft 4 is offset from the center plane 2 of the vessel in the direction of rotation of the propeller 3 to distance d in accordance with 10% inequality
     25%, where D is the diameter of the propeller.
    Installing the propeller 3 of the right rotation (clockwise) on the starboard side or the propeller of the left rotation (counterclockwise) on the left side of the ship's hull increases the propeller propeller efficiency, because the torus circulates in the opposite direction of rotation
    Screw, which has the effect of increasing the speed of rotation of the screw.
