Description

In the proposed horizontal-mounted wind turbine with a rotatable casing and with grooved blades, the latter are made with double walls forming gaps and cavities, which connect the working and non-working halves of the blade, which are one and the same.

Jets of air from the wind, producing pressure on the working half of the blade, not covered by the casing, pass into the cavity of the non-working half of the blade, covered by the casing. The reactive pressure from the air stream emerging from oppositely spaced cracks in the cavity of the non-working half creates additional pressure on the blade in preventing its rotation.

In FIG. 1 shows a top view of a horizontal wind turbine blade; FIG. 2-horizontal section of the blade; FIG. 3-vertical, its cut; FIG. 4 is a side view of the blade; FIG. 5 - a perspective view of a horizontal wind turbine.

A horizontal wind turbine consists of a series of grooved blades fixed on the shaft, located in a separate horizontal plane and covered on the non-working side by a protective casing I.

Each blade consists of two symmetrical, backward halves I9 and is made with double walls: outer 1 and inner i 2, forming cavities 6, 8 and slots 4, which narrow from the end of the blade to the middle, where both walls merge into one. The cavities 6 and 8 of the working and working half are provided with a common longitudinal partition 3. On the open side of the grooved blade there are transverse ribs with curved blades 5, forming slots 7.

Jets of air from the wind producing pressure on the blades 5 of the working half of the blade through the slots 7 enter the internal cavity 6, where they put pressure on the partition 3 and, slipping along the latter, pass from the cavity 6 of the working half of the blade into the cavity 8 between the internal 2 and the outer 1 walls of the non-working half of the blade, from where the air jets emerge through the slots 4, produce a reactive action on the blade. Thus, both halves of the blade are doing the same work, one working one, walking along the wind under the pressure of air jets from the wind, the other non-working, going up against the wind-reactive pressure

slits of the same air flow, which creates additional pressure on the blade in the direction of its rotation.

The blades 5 are arranged so that within 180 ° they take the blow of the air stream. The ends of the blade are bent and take on themselves a blow of air flow within 90 °.

The blades are mounted on the shaft 9, which is directly coupled to the gear wheel 10 by the gear wheel 10.

In order to increase engine power, an npoi and windscreen protective casing 11c with a counterweight 12 and a rudder 13 is inserted. The protective casing xvll quarter circumference protects half of the blade going against the wind. The protective cover is always automatically set against the steering wheel.

Since the blades are located in the horizontal section, the blow of the air flow in the blades 5 is perpendicular rather than tangential, which increases the engine power.

A large area of blades and burnout, subject to perpendicular pressure, air flow, reactive air from the non-working blade half, and the absence of gear teeth all contribute to an increase in engine power.

The subject matter of the invention.

Claims (2)

1. A horizontal wind turbine with a rotary casing and with grooved blades, characterized in that the components of a single unit — the working and non-working half of the grooved blade — are made with double walls 1, 2, forming slots 4 and cavities 6 and 8, communicating with each other, of which cavity 6 in the working half of the blade, not covered by the casing, is designed to perceive air jets from the wind that produces pressure on the said half of the blade, and to transfer these jets into the cavity 8 of the non-working half of the lasperga, covered by the casing, with uu air therefrom through the gap 4 formed was used the reaction pressure from these jets produced by them in the opposite direction to flowing through the slit 4 air to produce additional Yelnia pressure on the blade in its direction of rotation. 2. The form of the wind turbine according to claim 1, which differs from application, for receiving pressure from the wind by the working half blade and air passing into the cavity 6, transverse ribs with curvilinear blades 5 forming the slots 7, which cavities in the working and non-working half blades are equipped with a common a longitudinal partition 3, perceiving in 1, the working blade blade pressure from air jets that have passed through the said slots 7. fig Figz
