Abstract

The circular end plates in the Savonius rotor are modified in favour of a higher rotational speed in such a way that the novel shape of the end plates extends parallel to the rotor shells. However, the end plates have a rectilinear shape via the wind inlet into the rotor shell.

Description

Veränderung der kreisrunden oder abgerundeten Rechteckform der Endscheiben des Rotors, zwischen denen die beiden Rotorschaufeln liegen, in eine spezielle, die den Rotorschaufeln angepaßte Form. Durch diese Formgebung wird der Wirkungsgrad des Rotors, im Vergleich mit anderen Endscheibenformen, wesentlich verbessert.Change the circular or rounded rectangular shape the end plates of the rotor, between which the two rotor blades lie in a special one, which is adapted to the rotor blades Shape. Through this design, the efficiency of the Rotors, compared to other end plate shapes, essential improved.

Claims (3)

1. Die Veränderung der Form der beiden Endscheiben ist dadurch gekennzeichnet, daß sie parallel zur jeweiligen Rotorschale verläuft von A bis zum Punkt D (Fig. 1).1. The change in the shape of the two end plates is characterized in that it runs parallel to the respective rotor shell from A to point D ( Fig. 1). 2. Die Form der Endscheiben ist weiterhin dadurch gekennzeichnet, daß ab Punkt D die Endscheibenform die Verlängerung der Linie C bis D annimmt bis zum Schnittpunkt mit der Linie A über E in Punkt F.2. The shape of the end plates is further characterized in that from point D the end plate shape assumes the extension of line C to D to the point of intersection with line A via E in point F. 3. Über dem Windeingang der Rotorschaufeln endet die Rotorabdeckung durch die Endscheiben mit der Linienführung A bis F.3. Above the wind inlet of the rotor blades, the rotor cover ends with the end disks with the lines A to F.
