Abstract

The motor is a vertical rotation axis wind or water driven device comprising a central column with a rotating blade support structure in which are mounted three or more blade assemblies, each consisting of a main blade, a control blade and a cam system. Each of the blade assemblies is able to rotate freely within the support structure with complete independance from each other under control of individual cam systems located on the support structure at each blade assembly mounting.

Description

SPECIFICATION The windyne wind power extraction mechanism The WINDYNE is a wind power extraction mechanism in which vertical aerofoil surfaces produce a rotational output due to their cyclic alteratioan of angle of attack with respect to the relative wind axis.
The vertical aerfoil surfaces are comprised of a main blade and a control blade, the pair comprising a blade The control blade serves the following two functions: (1 ) to orient the main blade generally into the relative wind and (2) to enable the main blade to generate an aerodynamic force tending to rotate its supporting structure as a result of the variation of control blade angle during this rotation. Each blade assembly is free to rotate about the aerodynamic centre of its respective main blade with angular variation of the control blade effected by a fixed cam-type mechanism attached to the supporting structure at each blade assembly mounting. The windyne is in consequence "automatic" in its operation; able to start from rest and run in either direction irrespective of its initial position or wind direction.A minimum of at least three equi-spaced blades are employed in the windyne but the number of blade assemblies can be increased with only practical considerations setting a limit in order to increase the output power.
1. Unlike previous windmill designs it employs completely independent and freely rotating balanced vertical blade assemblies each comprising a main aerofoil sectioned power blade and its associated control blade in order to extract power from the flow of wind, water or other fluids through the machine.
la. The control blade mechanism causes rotation of the blade support structure to occur in one desired direction (resulting from the handing of the control blade actuating mechanism) during gas or fluid flow through the device and irrespective of any variations in the direction of such flow.
ib. The machine's blade assemblies are selforienting and roatation of the support structure is self-starting from rest.
2. It can be readily protected from damage resulting from excessive rotational velocity by means of the progressive reduction of the range of control blade incidence with respect to the main blade on each blade assembly resulting in turn in the lowering of the fluid dynamic force experienced by each main blade.
2a. It can be readily brought to a zero power (or 'feathered') condition to permit, for example, servicing to be carried out, by reducing the control blade's incidence with respect to its main blade completely to zero on each of the blade assemblies.
