FIELD: shipbuilding.
SUBSTANCE: invention can be used in production of screw propellers of surface and underwater crafts. For active control of water-borne means include transmitting torque from drive shaft on propeller shaft and angular position change propeller shaft with screw propeller, relative to drive shaft in space due to non-linear longitudinal configuration of edge lines of said shafts. Change in position of propulsion shaft relative to drive shaft is carried out by exposing fastening element, which is installed on propeller shaft, paired alternating-sign power loads.
EFFECT: higher manoeuvrability and reliability of active craft control.
