METHOD AND DEVICE FOR REDUCING AZIMUTHAL TORQUE AFFECTING PROPULSION GONDOLA UNIT OR AZIMUTHAL MANEUVERING DEVICE Russian patent published in 2017 - IPC B63H25/42 B63H5/125 

Abstract RU 2610887 C2

FIELD: ship building.

SUBSTANCE: invention relates to an azimuthal maneuvering device. Method of creating azimuthal maneuvering device (1) consists in that initial point of first fairing (4) is located at distance (y) behind vertical axis (3) of rotation. Distance (y) is within the range of 0.1D≤y≤2D meters, preferably within the range of 0.5D≤y≤1.5D meters, where D is diameter of the screw propeller. Herewith fairing (4) is located onto casing (2) behind axis (3) of rotation, is directed downward and is made in the form of an elongated blade in the form of a plank to extend behind axis (3) of rotation along gondola casing (2) nearby its rear end (5).

EFFECT: invention reduces the risk of grounding.
