The invention relates to shipbuilding, namely to fin movers,

The two-cavity fin propeller is known, consisting of two single-celled flexible fins, kinematically connected with a common hand drive.

The disadvantage of this drive is its low efficiency (lack of reversing).

A fin mover is known, containing a pair of blades, the ends of which are made in the form of flat convex surfaces that form wing profiles.

The disadvantage of this drive is also its low efficiency (lack of reverse).

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

This goal is achieved by the fact that the upper and lower ends of the blades are rigidly interconnected by U-shaped plates attached to the tailor, which allows the ship to reverse.

On fig.T depicted propulsion Assembly with the baller, side view; figure 2 - section aa in figure 1; on fig.Z - view B in figure 2,

The proposed propulsion unit contains blades 1 mounted in a vertical plane at a certain distance from one another, and plate 2 connecting the upper and lower ends of the blades 1 to one another. At the same time horizontal sections

The blades 1 are made in the form of an aircraft wing profile, and the plates 2 are connected to a puller 3 with a drive (not shown) providing angular oscillations of the blades 1 in the horizontal plane with a given span and frequency.

The mover works as follows.

If it is necessary to move the vessel, the actuator (not shown) performs angular oscillations of the blades 1 in the horizontal plane and informs some of the water’s acceleration directed from the top of the oscillation angle of the propeller to the arc, as a result of which the force of the vessel as the driving force of the driving force, the driving force of the driving force lies in the plane of the bisector of the angle of oscillation of the diametrical plane of the driving force and is directed from the arc to the top of the angle of movement of the driving force.
