Abstract
The wind power generator comprises a central vertical shaft (A) with four pairs of radial spokes (D). Each pair carries the vertical shaft (A') of a Flettner-type rotor (C). Radial further outward extensions of the upper spokes (D) each carry a vertical shaft of a Savonius-type rotor (F). - The shafts are coupled either via friction wheels (E',E) to rotate in opposite directions, or via belt pulleys to rotate in the same direction. Power take-off is from a pulley (B) on the central shaft. FL.(1/2)

Bovenzicht van halve 7Werking-de wind (ongeacht uit welke richting) brengt de Savoniusrotor in beweging. E en E laten de keuze van een andere omwentelingssnelheid voor C toe. C draait om as A dankzij het Magnuseffekt uitgeoefend op zijn flanken.

30 Er moeten minimum twee Flettnerrotors aanwezig zijn om zelfstartend te fungeren.
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.

60 De diameters van de eindplaten op de Savonius- en de Flettnerrotors moeten in gepaste verhouding staan met de respectievelijke rotors.
70 I stelt een overbrenging van SR naar FR door middel van een wrijfkoppeling. F en C draaien hier in tegengestelde richting. Humsnelheidsverhouding is dezelfde als de verhouding van hun-diameters.
8 II stelt een overbrenging van SR naar FR door middel van een riem en riemschijven. F en C draaien in dezelfde richting, hum snelheden verhouden zich zoals hun diameters.

1to De centrale as A mag ingekleed worden door een Savoniusrotor.
1'2c Men mag de Savoniusrotors (F, G) alsmede hun koppeling (E, E) afschaffen en de Flettnercilinders C gelijktijdige ombouwen in Savoniusrotors. In dergelijk geval kan er sprake zijn van een zuivere combinatie Flettner-Savonius.

30 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 weakened considerably by the rotors passing by.
<Desc / Clms Page number 2>
60 The diameters of the end plates on the Savonius and Flettner rotors must be in an appropriate relationship with the respective rotors.
70 I proposes a transmission from SR to FR by means of a friction clutch. F and C rotate in opposite directions here. Speed ratio is the same as the ratio of their diameters.
8 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.
90 In the drawing, the top view was taken with
EMI2.1
two and the side view with four Flettner rotors are presented. t 100 The axes A, 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.
1to The central axis A may be dressed by a Savonius rotor.
1'2c The Savonius rotors (F, G) as well as their coupling (E, E) may be removed and the Flettner cylinders C simultaneously converted into Savonius rotors. In such a case there may be a pure Flettner-Savonius combination.
