Description

The invention relates to shipbuilding, namely to propulsive-steering devices of a vessel.

The purpose of the invention is to increase the efficiency of the device.

Figure 1 shows a propulsive steering device, a cross-section; figure 2 - section aa in figure 1.

The propulsion device of the vessel contains a flow channel 1, spaced in the hull 2 of the vessel perpendicular to its diametral plane, and extendable propulsion columns 3 and 4 mounted on both sides of the flow channel 1 can be rotated in the horizontal plane . In this case, the axis of rotation of the screws 5 of the steering column 3 and 4 are offset relative to the longitudinal axis of the water-flow channel 1 in different directions in the horizontal plane. In the outlet sections of the water-flowing channel 1, rotary valves 6 are placed to block it, kinematically interconnected for their parallel simultaneous rotation, with axis 7 of rotation of the valves 6

GP

offset from the axis of the water channel I in the bow of the vessel.

The device works as follows. To create a pull directed along the axis of the water-flowing channel 1, the propulsive steering columns 3 and 4 are pulled out of the hull of the vessel and installed along the direction of the longitudinal axis of the water-flowing channel 1. One of the propulsive steering columns is activated, for example, column 3, flow

water from the screw which is directed to the board of the vessel. At the same time, the valves b, under the action of water flow, turn along the longitudinal channel 1 along the longitudinal axis. After turning the valves 6, the propulsive steering column 4 is switched on from another

board, the flow of water from the screw which is directed from the side of the vessel. Flows of airflows, propelled by screws 5, are separated by gates 6, ensuring efficient operation of both screws in the steering mode of the vessel. On

During the ship’s movement, the propulsive steering columns are installed parallel to the vessel’s DP, and the dampers 6 are installed along the ship’s side, closing the water-flow channel 1, and thus reducing the resistance to movement of the vessel.
