Abstract

A wind or water powered turbine has a longitudinal concave multi vane rotor 1 a housed in a unit which uses aero foils and the venturi effect to accelerate and direct the propulsive flow to the rotor. The unit also has an aerofoil 1c which shields the returning vanes from the negative effect of the propulsive flow and in combination with other vanes 1b, 1d channels a portion of the propulsive flow to drive the returning blade. The rotor may incorporate folding vanes which are used to reduce the drive at times of excessive fluid flow speed (Fig 2) and incorporate the rotor and stator of an electrical generator.

Description

PAGE 1 TITLE.
A POWER GENERATING TURBINE CAPABLE OF BEING DRIVEN BY WIND OR WATER.
BACKGROUND.
The invention relates to a power generating turbine. Many conventional wind/water powered generating turbines are large, obtrusive, noisy and dangerous to human and animal life. They are also not very versatile in the uses to which they may be put.
STATEMENT OF INVENTION
The invention relates to an efficient power generating turbine which may be driven by wind/air/gas or water. It is theap and simple to construct, compact, less obtrusive in respect of appearance and noise and more versatile in use than a standard windmill. It also presents less of a danger to human and animal life from exposed rotating blades. It may be used vertically or horizontally and units may be stacked and linked. It incorporates aero foils to direct and accelerate the flow of air/water taking advantage of 1. direct air flow.
2. accelerated flow over aerofoil/s 3. the venturi effect.
4. propulsion from the circulation of air to the returning vane.
5. The protection of the returning vane from the negative effect of the source of the propulsion.
PAGE 2 ADVANTAGES.
1. The invention may be used domestically or in small or large commercial applications.
2. The invention is simple to manufacture domestically or on a commercial basis.
3. The invention is less obtrusive both visually and in noise, and also more compact than a conventional windmill.
4. The invention is safer as it does not involve the use of large exposed rotational blades that present a danger to humans and wildlife.
5. The invention may be used for the generation of electrical power or for the direct propulsive drive of vehicles on water or land.
6. To achieve efficiency the invention uses aero foils to accelerate and direct the propulsive flows to maximize power and to circulate that flow in propelling the returning vane.
7. The design of the invention protects the returning vane from the negative effect of working against the propulsive flow thus increasing power and efficiency.
8. The vanes may be constructed to fold in order to reduce the drive power and to reduce speed during excessively strong propulsive flow.
9. The core of the turbine rotor may incorporate the electrical rotor and stator as an integrated part of its construction.
10. An additional aerofoil may be incorporated to enhance the venture effect.

DETAILED DESCRIPTION
A power generating turbine propelled by wind/gas/water having a longitudinal concave multi vane rotor. (fig Ia) This is incorporated into a housing which consists of aero foils which accelerate and direct the propulsive force onto the concave face of the turbine vanes.( Fig lb and 1 bi) The invention also incorporates an aerofoil which, as well as accelerating and directing the flow, protects the returning vane from the otherwise negative effects of the propulsive force. Fig ic) Another foil also direct and accelerates the flow to the returning vane, thus increasing the efficiency and power of the unit. (lb and id) . The rotor may also incorporate folding vanes to reduce the drive at times of excessive wind/water speeds (2ai) and also incorporate an electrical rotor (2aiii) and stator (2ii) for the generation of electrical power.
