FIELD: mechanical engineering.
SUBSTANCE: invention is relevant to shipbuilding and can be used on floating facilities both for surface vessels and for underwater ones. V-like twin screw mover for floating facilities in variant of surface vessel includes screws placed at angle on transom plate in aft part. They are controlled with the aid of gear-motor drives intended for regulation of speed and direction of screw rotation. Screws together with these gear-motor drives are moved at various angles within horizontal plane by force of additional gear-motor drives intended for regulation angle position of screws, which are joined with them. All gear-motor drives are connected to the central system of surface-vessel control via unit for control of drivers. In variant for surface vessel transom plate equipped with gear-motor drives that are provided with screw movers is suitable for turning within vertical plane with the aid of gear-motor drive for angular plate turn, which is fastened to plate axis.
EFFECT: increase of efficiency coefficient, rate of sailing and maneuverability of floating facility as well as exclusion of cavitation are achieved.
