Abstract

The aim is to convert wind energy into a steady flow regardless of the wind direction; this is achieved by having vertical vanes on a horizontally- disposed rotor within a circular assembly of vanes which direct the wind flow on to the rotor vanes so driving the rotor. An inner set of fixed vanes is arranged to pass the flow across the centre and to pass through the inner vanes once more, the inner vanes being angled oppositely to the outer vanes so as to direct the flow again on to the working surface of the rotor vanes giving an additional thrust before discharging through the outer fixed vanes.

Description

SPECIFICATION The Goodridge wind turbine Whereas the convenional windmill has a vertical rotating plane the Goodridge turbine has an horizontal rotor thus avoiding the necessity to turn into the wind this makes it a suitable rooftop power unit.

The power unit for this windmill is enclosed in a circular housing formed by two dicss one on top one at bottom the outer edges turn up on top and down at bottom thus increasing the air pressure through the dics when the wind blows.

Between these sloping edges are fitted flat vertical vanes as shown at (A in diagrams) radiating inwards at an angle of approximately 45 degrees to a line drawn from their leading edge and the centre of the disc.

Through the centre of the disc a shaft is passed on roller bearings midway up this shaft is a flat wheel the spokes almost reaching the fixed vanes to these spokes are fitted a ring of vertical vanes having a concave bend from front to back the edges being in straight line from the centre of the shaft, the concave face of the vane faces the angled fixed vanes thus receiving the full force of the deflected wind.

Behind the rotating vanes are the two sets of vanes one attached to the upper disc the other to the lower ending just short of the wheel spokes and set at an angle 45 degrees but opposite in directiont to the outer vanes as at (B in diagrams) the power from the centre shaft is available for driving generators, pumps, etc.

This system is non directional the wind being directed onto the rotory vanes even if the wind swings around the clock when the wind passes through the outer vanes it is directed onto the rotating vanes and causes then to revolve then passes through the second line of fixed vanes, on passing across the centre it enters the inner ring of vanes and as these are set at the opposite angle to the outer ring of vanes the air is directed onto the concave side of the rotory vanes giving another boost to the unit befor passing out through the outter vanes and away.

1. The low profile and nondirectional power unit is different to other windmills being verticle axis the rotor lies horizontal the blades being driven forward by direct pressure and not by deflection, as in standard practice and being fully enclosed inside the housing males it suitable for rooftop use.
