Abstract

This windmill generator produces electrical or mechanical power to be used elsewhere. It has Flettner rotors on the outside circumference of the carousel. The carousel is formed from two horizontal plates in which the axes of the rotors are positioned. The central axis and drive shaft has a pulley, below the lower plate, and this pulley is used to couple the useful energy to a generator. - In addition to the four Flettner rotors, there are also four semi-Savonius rotors, each mounted half way between the central shaft and the Flettner rotors. The Flettner rotors act as self-starters to initiate the rotation of the assembly in the required direction.(0/1)

   40 Stilstaand op A bouwen de Flettnerrotors geleidelijk een passend startkoppel op door middel van de in de wind versnellende Savoniusrotors. 



   50 Gedurende een deel van de omwenteling om as A heeft men een negatief koppel. Dit wordt door de   som   der positieve koppels ruimschoots overtroffen vermits het negatieve koppel op een plaats geproduceerd wordt waar de wind reeds sterk afgezwakt is door de voor de wind passerende rotors

 en de Flettnerrotor moeten in gepaste verhouding staan met de respectievelijke rotors. 



  7a I stelt een overbrenging van SR naar FR door middel vaneenwrijfkoppeling. F en C draaien hier in tegengestelde 
De diameters van de eiiadplaj ? erichting. Hun snelheidsverhouding is dezelfde als de verhouding van hun diameters. 



     8a II   stelt een overbrenging van SR naar FR door middel van een riem en riemschijven. F en C draaien in dezelfde richting, hun snelheden verhouden zich zoals hun diameters. 



   9  Op de tekening werd het bovenaanzicht met twee en het zijaanzicht met vier Flettnerrotors voorgesteld. 



     100'De   assen A,   A'en   A"zijn alle onderling evenwijdig en loodrecht op het aardoppervlak : men mag hier dus spreken van een verticale as turbine alhoewel andere posities eventueel gebruikt mogen worden.   lil,   De Flettnerrotors kunnen aangedreven worden op verschillende manieren : door mechanische, electrische of andere energie te leveren van buiten af of zoals verder zal verklaard worden, door energie die rechtstreeks uit de wind ontnomen wordt door Savoniusrotors waarvan een paar mogelijke oplossingen werden getekend op de figuur en uitgelegd in de tekst.

   Het spreekt vanzelf dat deze rotors, of eventueel andere vormen van   windenergie omzetting   met hetzelfde doel, op andere plaatsen op het toestel kunnen worden aangebracht, bv Savoniusrotors tussen de bevestigingsarmen D, die zodoende de Flettnerrotors met riemen (of andere zoals   tandwielem en   assen) aandrijven
12a De achter de wind passerende Flettnerrotors bevinden zich   gedurende t80   (die    samenvallen   met de   11800   negatief koppel) in de energieschaduw van het   WEOS.   Het negatief koppel wordt daardoor veel kleiner dan het positieve vooraan. Dit geeft een eerste positieve lift. 



  De voor de wind passerende rotors buigen de luchtstroom   90 om daar-   door wordt de helft van de   180, 01 achter   de wind positief, zij het met verminderde kracht, voldoende om ongeveer de negatieve werking van het negatieve kwadrant op te heffen. Dit is een tweede positief punt. 



    Als   men het geheel der Flettnerrotors aan het draaien brengt rondom de centrale as A van het   WEOS.   kan men vermoeden dat de luchtstroom, over het geheel dankzij het Magnuseffekt op dit geheel, een aerodynamische kracht uitoefent in dezelfde zin als deze van de rotatie van het sygteem.

   Operation: the wind (regardless of which direction) moves the Savonius rotor. E and E "allow the selection of a different speed of revolution for C. C revolves around axis A thanks to the Magnus effect applied to its flanks.

3a At least two Flettner rotors must be present to function self-starting.



   40 Standing at A, the Flettner rotors gradually build up a suitable starting torque by means of the wind-accelerating Savonius rotors.



   50 During part of the revolution about axis A, one has a negative torque. This is amply surpassed by the sum of the positive torques since the negative torque is produced in a place where the wind has already been greatly weakened by the wind-passing rotors

 and the Flettner rotor must be in appropriate relationship with the respective rotors.



  7a I proposes a transfer from SR to FR by means of a rubbing clutch. F and C rotate in opposite directions
The diameters of the eiiadplaj? direction. Their speed ratio is the same as the ratio of their diameters.



     8a II proposes a transfer from SR to FR by means of a belt and pulleys. F and C rotate in the same direction, their speeds are proportional to their diameters.



   9 The drawing shows the top view with two and the side view with four Flettner rotors.



     100'The axes A, A'and A "are all mutually parallel and perpendicular to the earth's surface: one can therefore speak of a vertical axis turbine, although other positions may be used. Lil, The Flettner rotors can be driven in different ways: by supplying mechanical, electrical or other energy from the outside or, as will be further explained, by energy taken directly from the wind by Savonius rotors, of which a few possible solutions were drawn in the figure and explained in the text.

   It goes without saying that these rotors, or possibly other forms of wind energy conversion for the same purpose, can be mounted in other places on the device, eg Savonius rotors between the mounting arms D, which drive the Flettner rotors with belts (or others such as gear wheel and shafts)
12a The Flettner rotors passing behind the wind are located during t80 (which coincide with the 11800 negative torque) in the energy shadow of the WEOS. The negative couple is therefore much smaller than the positive one at the front. This gives a first positive lift.



  The wind-passing rotors bend the airflow 90 so that half of the 180.01 behind the wind becomes positive, albeit with reduced force, sufficient to cancel out approximately the negative effect of the negative quadrant. This is a second positive point.



    If one turns the whole Flettner rotors around the central axis A of the WEOS. it can be presumed that the air flow, in general thanks to the Magnus effect on this whole, exerts an aerodynamic force in the same sense as that of the rotation of the system.

  This reason true. is a third In most circumstances there will be a significant increase in efficiency compared to a classic WEOS with blades,
