Title: Wind rotor with air flow guide stator
Inventor: HOEPPNER WILLI
IPC: F03D3/04
Filed: 1981-07-02
Abstract: The invention relates to a "wind rotor with air flow guide stator", comprising a vertically arranged cylindrical wind rotor, provided with drive blades of optimum efficiency, which is enclosed by an air flow guide stator, with air flow guide blades pointing in the wind rotor direction of rotation, angled at approx. 40 DEG  and running in a nozzle shape, the air flow guide stator, according to the invention, having the function of guiding the air flow - wind - against the wind rotor drive blades, in order to achieve optimum utilisation of the wind power, that is a high acceleration of the wind rotor and hence a corresponding wind energy yield due to the maximum air flow surface thereby achieved. Without the air flow guide stator, this cannot be achieved, since not only is the concentrated aligned air flow absent, but that part of the wind rotor moving counter to the air flow (wind) is braked. Intended as an energy-generating combination or alternate function, it is proposed to provide the necessary roof covering of the "wind rotor with air flow guide stator" with a pitch roof equipped with solar cells oriented to the "South". One embodiment of the invention is shown in the drawing and is further described below. Fig. 1 shows a section through the wind rotor, Fig. 2 the air flow guide stator/section enclosing the wind rotor. <IMAGE>
