Description

Bladed ship thrusters are known using blades rotating around its vertical axis.

A distinctive feature of the proposed propulsion unit is that the blades rotating around the vertical axis are located in parallel on the ends of the horizontal shaft, oscillating around its longitudinal axis.

To oscillate a horizontal shaft with pair-wise blades, an "extra eccentric" is used, connected with the shaft by means of levers. In order to improve the direction of movement of the vessel, the eccentric is connected with a control lever, the help of which changes the position of the eccentric.

The scheme of the proposed engine is depicted in the figure; below the dotted line shows the view of the blades. According to the arrow L.

On the horizontal shaft / there are fixed blades 2, and the axes of the blades form a certain angle p with each other. The shaft 1 is supported by bushings 3 fixed on the end of the vertical shaft 4 driven by the motor 5. To the shaft I are attached levers 6 with rollers 7, which are pressed to the side surface of the eccentric 8. The latter is fixed on the tube I equipped with a lever / O control instead of an eccentric control, a hinge mechanism can be used).

The motor 5, through the vertical shaft 4 and the bushings 3, causes the horizontal shaft U to rotate around the vertical axis, which simultaneously, due to the presence of the eccentric S and levers b, receives, together with the blades, an oscillatory motion about the horizontal axis. If the blade at any position increases the angle of attack, then, after turning by 180 °, it has the same angle of attack, b, relative to the medium in which the propulsion device works; this creates an abutment causing proper vessel traction.

Due to the oscillations of the blades 2, which synchronously enter the water, then come out of the water, they can be given a wing bearing profile, unlike other propulsion units, which always work with one side.
