To accomplish this, the cables must pass through diagonal guides 18 and have sufficient slack to allow appropriate opening of one sail and proper closure of the other. The measurement of a side of the hub 18 (AD) is one half of a side of the sail 10 (AB). SUMMARY OF THE INVENTION The present invention is specifically directed to overcome the above-enumerated problems in a novel and simple manner. These problems can be partially alleviated by adding a second rotor in a stacked arrangement whereby the rotors are offset by ninety degrees. Advancing sail 10d is partially deflated. Disassembly of the mast is accomplished by the detachment of the wire braces 42 from the bottom flange 48b. The mast 30 can then be partially separated to reveal the power-shaft coupling (not shown). 8) upon which four wire braces 42 are attached. The mast braces 42 are stretched tightly between the two flanges 48a, 48b with turnbuckles (not shown).

The mast 30 terminates at both ends with a flange 48a, 48b (FIG. The action of the sails 10 is linked in pairs to control their corresponding shapes (FIG. The sails are linked in oppositely disposed pairs by cables and guides. The sails 10 are joined together in pairs (FIG. The rotor is elevated and supported by a mast 30 made of two polyvinyl chloride (PVC) tubes approximately 10 cm in diameter and about 6 m in length when joined together. The energy derived from lift type systems is typically expensive. In the present invention, wind energy is converted to rotational motion by the provision of sails 10 that selectively open and close depending on their aspect to the wind. The invention resides in the provision of sails 10 that open and close opposingly in conjunction with a frame structure 12, 14 that supports, controls, shapes and rotates the sails 10 on a vertical shaft, and transmits the energy to the ground through a shaft contained in a mast structure.

The rotor comprises sails that open and close opposingly on a square wheel to alternately catch and ride wind as they rotate about a vertical shaft. Dolor lumbar cama . 5. The rim connectors 20 join the rim elements 12 together and provide a means for attaching the spokes 22,24. The preferred connector 20 consists of a retaining ring 50, a dowel 52, a spoke attachment bracket 54, and a spoke attachment pin 56. The retaining ring 50 is fastened at right angle to the dowel 52 and secured with a bolt projecting from the retaining ring 50 and running through the center of the dowel 52. The spoke attachment bracket 54 is sandwiched between the dowel 52 and the retaining ring 50, and projects outwards at forty-five degrees. The mating of the rim 12 is accomplished by sliding the retaining ring 50 onto the extended portion of the a rim 12 until it stops at the stop screw 58. The connecting rim element is placed onto the dowel 52. The attachment of the spokes to the spoke attachment bracket 54 by the spoke attachment pin 56 holds the adjacent rim members together.
The top portion (about 50 cm.) of the power shaft 32 is a solid steel shaft about 2.5 cm. The Savonius design can be described as a barrel cut in half lengthwise and offset to form two scoops mounted on a vertical shaft. The Savonius Rotor, or `S` rotor, has overcome much of this complexity as a result of its vertical shaft design. The threaded end extends beyond the top of the mast and is threaded into the bottom axle flange 26b of the rotor, thereby providing a means of attaching and detaching the rotor from the mast 30. Preferred direction of rotation and shaft threading must conform to prevent self-detachment during operation.

Two major deficiencies can be sighted in this design: (a), torque is unevenly distributed during operation, and (b), if it is improperly oriented to the wind, starting torque is zero. Any direct mechanical means of delivering power to the ground must avoid causing the head to rotate out of the wind when resistance is encountered during work loading.

The different drag characteristic of the two shapes causes the rotor to turn in a preferred direction. Wind (indicated by the arrow) encounters each sail at a different angle as they rotate into and away from it. Receding sail 10a is completely inflated. The sails that are receding from the wind form scoops that reciprocally draw the advancing sails into a wing.
The art comprises past designs that have selectively diverged in function and could be categorized as: lift and drag machines. A rigid, or fixed joint could eventually break. Quiste en la mano dolor . The cost and construction requirements remain much too high for the individuals who could best benefit from it. These individuals are typically people living in remote rural areas who need a reliable source of power for tasks critical to their well-being. Evidence for these drawbacks can be found in its failure as a product.
A second shorter `L` bracket, with a hole in its upturned leg, is fastened to the foot board 39 adjacent to each leg. The bottom flange 48b is attached to a hinged foot 38 (FIG. The operation is dependent on the proportion and arrangement of the rim 12, hub 14, guides 18, and sails 10. The proportion and arrangement of these components remain consistent while the size of the complete rotor assembly can vary according to desired power and local wind conditions. The two remaining diagonal corners are fastened to cables 16. The sails 10 communicate by the provision of the cables 16 and cable guides 18 to position and limit the open and closed phases. 1) by cables 16 that communicate through cable guides 18 to control, position, and limit the corresponding sails. FIG. 2 is a top view of the invention in its preferred form showing the relative size of the basic components of the rotor.
FIG. 7 is a perspective view of the wind turbine from the side in its operating state that shows the sail phases of the rotor, and a fragmentary view of the power shaft and mast. An exception to this design of high speed machines is the Darrieus, which revolves on a vertical shaft. Dolor de espalda al lado derecho . Maintenance and assembly are achieved by removing these screws and extracting the power shaft. Ample starting torque supplied by the wind turbine of the present invention precludes the need for complex gear reduction at the output end. Early windmills required almost a small gale for the blades to move steady and well. The western windmill with its horizontal axis and blades rotating in a vertical plane was believed to be an independent invention from around the 12th century. Their axis was vertical but their blades rotated in a horizontal plane. Pumping water for the house and the livestock is an example of an obvious task, but other important tasks can be cited as well.
The need for direction finding, speed control, complex transmissions, and intense lubrication are but a few of these complexities. Although there has been substantial effort to improve its efficiency, the Savonius design has not satisfied the need for a simple, low-tech solution for the problems it intended to eliminate. This improvement, however, creates additional problems associated with its weight, balance, and expense. The bearing blocks 32 of the upper tapered roller bearings and the bottom ball bearing are fastened to the mast 30 with screws that extend through the mast 30 and into the bearing blocks. In the case of the Savonius, the tower must exceed the height of the rotor for top support. Wind speed of 5 meters per second is usually needed to supply ample power for pumping water from a 10 meter well. They are usually large, permanent structures dedicated to a particular function, such as, raising water, sawing wood, grinding grain and cement; and have been traditionally used for producing oils, dyes, snuff, paint, paper, and textiles.
FIG. 4 is a top view of the rotor frame structure.
High speed machines are used for electrical generation where low starting torque is less of a problem. It should be understood that the foregoing detailed description was made for the purpose of demonstrating the structure and operation of the invention with no unnecessary limitations to be understood therefrom. FIG. 4 is a top view of the rotor frame structure. Since the output is near the ground level, installation of appliances is facilitated. The mast 30 is held in a vertical position by four guy wires 34 anchored to the ground.

FIG. 8 is a perspective view of the wind turbine assembly in its operating state including the preferred mast arrangement. DESCRIPTION OF THE PREFERRED EMBODIMENTS FIGS. FIGS. 6, 7 shows the sails in their respective phases. Lift machines having high speed operation with low starting torque, whereas the opposite is more the case for drag types. Because the wind turbine described above is relatively slow moving, durable, quiet, and easily dismantled before hurricanes, it is suitable for operating near buildings and roads. Full scale use of wind power emerged in Persia in the 7th century. All of these objects contribute to increased torque and swept area, resulting in greater power potential. In addition, the total swept area of the windmill remains low. The proportions are as follows: The sails 10 form a square and determine the size of the other components.
