FIELD: shipbuilding.
SUBSTANCE: invention relates to shipbuilding, namely to ship propulsion and steering systems. Propulsion-steering complex (PSC) of the displacement vessel contains a set of propellers and rudders, which interact with the ship's hull and are installed in its aft, connected with the central control post. PSC is also provided with elements with a wing profile to form a propeller screw flow (PSF) and further includes wing elements of the PSF shaper having an arcuate profile that repeats the shape of the aft portions of the hull of the vessel. Contours are placed on opposite cheekbones symmetrically to the vessel's diametrical plane and fixed to the hull of the ship by means of rib plates which are installed in a direction transverse to the diametral plane. Wing elements with an arc-shaped profile are made with a leading edge directed towards the incident stream, and a trailing edge directed towards the propeller.
EFFECT: increase in controllability and maneuverability of the vessel is achieved with a decrease in its speed.
