Abstract

A vertical axis wind turbine comprises two or more vertical or inclined blades 2 of aerofoil section mounted at their upper and lower ends on pivots 1 close to the blade leading edge so that their angle relative to the wind can be varied. The blades are provided with mechanical e.g. a cam track 3 and follower, electrical, hydraulic or aerodynamic mechanisms which may vary their angle to the wind so as to extract power from the wind or to offer minimum resistance to the wind and impart a turning force to the disc 4, arm or structure upon which the blades are mounted. The blades, their pivots and all associated attachments form a cone or cylinder assembly which is mounted in a vertical shaft 5, via bearings 6, a suitable distance above the ground to work in unobstructed wind.

Description

1- 2356431 THIS INVENTION RELATES TO AN IMPROVED VERTICAL AXIS WIND
TURBINE Vertical axis wind turbines have not found favour generally because of their lack of efficiency, ungainly appearance and the very large sizes necessary to obtain a reasonable power output. Vertical axis machines usually fit into the category of DRAG machines, whereas the more common horizontal axis wind turbines arc LIFr machines and are therefore more efficient. All current wind turbines arc open to criticism for their visual impact when sited on open landscapes where they work best.
Acco rding to my invention, a vertical axis wind turbine is provided with two or more vertical or inclined aerofoil section blades pivoted at their upper and lower ends at a point close to the leading edge of the blade.
This blades assembly represents a cone or cylinder form which is mounted via bearings on a central vertical shaft a distance above the ground to ensure free and unobstructed exposure to the wind.
A specific embodiment of the invention will now be described by way of example with reference to accompanying drawing 1/2 and 2/2 in which-.Figure 1 shows the general layout of the machine.
Figure 2 shows a view of the blades from above, with the arrows representing the wind flows through the assembly.
Referring to the drawings, the pivots at the upper and lower ends of the blade 2 allow free movement of the blade 2 on its axis, so that given a free flow of wind, each blade automatically adopts an attitude of minimum resistance to the wind.
By means of a cam track and follower 3 or pushrod or other mechanical device or by meansof an aerodynamic device such as a tab fitted to the trailing edge of the blade or by means of electric actuators or servo motors or by hydraulic motors, the angle of each blade relative' to the flow of the wind is caused to move so as to give a driving force to the perimeter of the assembly and instigate a rotary movement. This angle given to the blade is varied according to where it is during its path around the perimeter of its arc of travel. On the upwind side, it adopts a positive angle and on the downwind side, it adopts an opposite angle so as to continue to provide a driving force to the assembly.
in the transition zones to the side, each blade is free to assume an angle which naturally gives minimum resistance to the wind. The construction of the machine may be arranged so that it resembles a round tower building with the rotating part, including the blades forming a cone on the top. This arrangement is visually pleasing and allows a useful space below the mechanism for storage, housing or other uses. Small versions may be mounted on a wheeled chassis as portable power generators.

Claims (3)

  1. A Vertical Axis wind turbine comprising two or more vertical or inclined blades of acrofoil section pivoted at their upper and lower ends in such a way that the blades are free to move on their pivots to assume any angle to the wind when actuated by such control forces as are applied to them.
  2. 2. A Vertical Axis wind turbine as claimed -in Claim 1, where actuating mechanisms of mechanical, electrical, hydraulic or aerodynamic kinds are applied to the blades so as to adjust the angle of the blades relative to the wind for the purpose of extracting power from the wind or for offering the minimum resistance to the wind.
  3. 3. A Vertical Axis wind turbine substantially as described herein with reference to Figures 1 and 2 of the accompanying drawings 1/2 and 2/2.
