zu einer Gebrauchsmusteranmeldung für ein horizontales Windradon a utility model application for a horizontal wind turbine

vom 7.4.1988from 7.4.1988

Anmelder: Michael SderraApplicant: Michael Sderra

Die Erfindung bezieht sich auf ein horizontales Windrad, das anstelle eines Savonius-Rotors verwendet werden kann.The invention relates to a horizontal wind turbine that can be used instead of a Savonius rotor.

Der Savonius-Rotor ist ein Windrad zur windrichtungsunabhängigen Nutzung der Windenergie. Er erhält seinen Drehimpuls hauptsächlich dadurch, daß Wind in das Innere des Rotors eintritt und ihn durchströnt. Eintreten und austreten tut der Wind dabei durch zwei öffnungen, die von den beiden Rotorblättern des Savonius-Rotors gebildet werden=The Savonius rotor is a wind turbine that uses wind energy regardless of the wind direction. It receives its angular momentum mainly from the wind entering the interior of the rotor and flowing through it. The wind enters and exits through two openings formed by the two rotor blades of the Savonius rotor.

Ein Nachteil dieses Rocors ist es, daß die Öffnungen bei einer Umdrehung des Rotors jeweils nur kurz vom Wind angeströmt werden.A disadvantage of this rotor is that the openings are only briefly exposed to the wind during each rotation of the rotor.

Der Erfindung liegt die Aufgabe zugrunde, die einströmende Luftmenge zu vergrößern, ohne das Durchströmen des Rotors deutlich zu behindern.The invention is based on the object of increasing the incoming air quantity without significantly hindering the flow through the rotor.

Erreicht wird dieses Ziel durch eine Anordnung von drei Rotorblättern (1), Dadurch erhält der Rotor eine dritte, f gleichgroße Öffnung, sodaß pro Umdrehung mehr Wind in den Rotor einströmen kann.This goal is achieved by an arrangement of three rotor blades (1). This gives the rotor a third, equally sized opening so that more wind can flow into the rotor per revolution.

In der Zeichnung ist der Erfindungsgegenstand in einem Ausführungsbeispiel in der Draufsicht dargestellt.In the drawing, the subject matter of the invention is shown in a plan view in an embodiment.

Horizontales Windrad mit drei Rotorblättern (1), deren Krümmung zur Rotorachse (2) hin zunimmt. Dadurch wird dem Luftstrom im Inneren des Rotors erleichtert von einem Rotorblatt auf das nächste zu wechseln. De? Durchfluß bleibt somit gewährleistet.Horizontal wind turbine with three rotor blades (1), the curvature of which increases towards the rotor axis (2). This makes it easier for the air flow inside the rotor to switch from one rotor blade to the next. The flow is thus guaranteed.
