Abstract

The drive has a wing 2 that can be turned to look like a vertical t. There is a vibrating slat 3 ahead of the wing 2 connected to the vibrating drive 5 through its mast. The axis I of the wing 2 is equipped with a control system 9, turning the wing leeward to the mast 4 of the slat 3. When vibrating the slat 3, the vibrations cause free vortexes to spin off the slat and after joining the airflow streamlining wing 2, the vortexes increase the flow speed on leeward side 10. The air pressure decreases on the leeward wing 2 side when the airflow speed increases, whereby a stand alone attraction power in the direction of ship movement is created.

Description

The invention relates to ship propulsion systems powered by wind power.

Known sailing vessel equipment having a mast and a gig, connected by a tubular elbow, rigidly secured to a vertical shipboard shaft. The equipment also has a shock absorber with one end attached to the gig and the other attached to the boat. The shock absorber shall have a rope connected to it at one end, the other end of which shall be connected to an on-board regulating lever integrated into the vessel's sailing equipment. The sail has a vertical notch at its rear edge, dividing the sail into driving and stabilizing parts (USSR a.l. No. 1253876).

The disadvantage of such Equipment is its lack of technical capability.

It is also known to have a ship having a hull and a propulsion consisting of side-mounted masts, pivoting vertically about the axis, and rotary gears electrically connected to the control system. The masts are hinged so that they can be tilted up to 30 ° from the vertical. The masts have folding gears electrically connected to the automatic control system, and the sails have end stops (USSR a.l. No. 1625779).

The disadvantage of such a technical solution is the lack of aerodynamic efficiency of the wind turbine.

The object of the invention is to increase aerodynamic efficiency.

The stated aim is achieved by making the following modifications to the known wind turbine, which has a pivot-rotating wing:

the wing is equipped with a swinging wing, coupled to a swinging gear, and the wing also has a control system capable of rotating the wing about its vertical axis downwind to the wing of the wing.

The authors are not aware of the solutions with the features of the proposed solution and therefore read it as having significant new features.

BRIEF DESCRIPTION OF THE DRAWINGS FIG. Figure 2 is a side elevational view of the propulsion machine with a partial section; top view.

The wind turbine has a rotatable wing 2 relative to the vertical axis 1. The wing 2 is provided with a pivoting wing 3 with its stem 4 via a pivoting gear 5, a crankshaft 6 and bevel gears 7 connected to the engine 8. The wing 2 further has a control system 9 capable of rotating the wing 2. the bottom 10 of the wing 10 to the mast 3 of the wing 3. The entire propeller is secured to the hull 11 by an axial tube 12 with a crankshaft 6 inside. The trim 2 has a trimmer 14 attached to the body of the wing 2 at variable angles. The lower limiter 16 serves together to secure the vibrating gear 5 of the wing 3 and the control system 9 of the wing 2. As the ship is moving, free air vortices 17 are formed at the wing 3 and airflow 18 flowing at the wing 2.

The engine works as follows:

The engine 8 of the ship's wing 3 is vibrated through the oscillating gear 5 by rotating it relative to the mast 4. Vibration from wing 3 separates the free vortices 17, which join the airflow 18 flowing over wing 2. By signal from vessel control system (not shown in the drawing), wing 2 control system 9 turns wing 2 downward 10 to wing 3 mast 4, side 4. vortexes 17 and join to airflow 18 flowing through wing 2. Connected vortexes 17 circulate about wing 2 in a closed loop and increase the velocity of flowing stream 18 of the downstream side of wing 2, thereby reducing air pressure here. On the windward side of wing -2, the velocity of stream 18 decreases and the air pressure increases. The change in pressure creates additional air pressure to wing 2 and additional thrust to the vessel. The amount of thrust can be adjusted by adjusting the vibration of the wing 3. The optimum propeller angle of attack is determined by the trimmer 14 by varying its angle with respect to the longitudinal axis of the propeller. With the trimmer 14 in the neutral position, the propeller stands up to the fluidized position and produces no pulling force.

Compared to the prototype, the aerodynamic efficiency of the propeller is enhanced by the fact that the pre-wing pivoting wing makes itself active by means of a pivoting gear and makes the entire propeller less dependent on the natural wind speed and direction. In low winds, engine speed can be increased, thereby increasing traction and boat speed. The wing axis control system contributes to the improvement of aerodynamic efficiency by ensuring that the rotation of the wing accelerates the flow on the downwind side of the wing and thus the thrust it generates.
