Description

Windrad mit Verstellflügeln Die Leistungsregelung von Windkraftanlagen erfolgt meist entweder mittels einer Fliehkraftdrehzahlregelung oder mittels einer Vorrichtung, bei welcher der Winddruck zum Verändern de#,-wirksamen Flügelkreisfläche oder zum Verdrehen der Flügel benutzt wird. Die letztgenannte Art um£aßt Verfahren, bei denen die Flügelverdrehung unter Verwendung von Stoßdämpfern durch Schub-oder Zahnstangen entgegen der Wirkung einer Federung erreicht wird.Wind turbine with adjustable blades The power control of wind turbines usually takes place either by means of a centrifugal speed control or by means of a Device in which the wind pressure to change the effective wing circle area or used to twist the wings. The latter kind of eating procedure, in which the wing rotation using shock absorbers by thrust or Racks against the action of a suspension is achieved.

Das Verfahren gemäß der Erfindung sieht dagegen die Verwendung von Flügeln vor, welche selbst aus federndem Material bestehen und durch Verbiegen um die Flügellängsachse ihren Anstellwinkel verändern. Die Biegung erfolgt durch den auf die Flügel wirkenden Winddruck, so daß bei steigendem Winddruck die Projektion der Flügelfläche in die Windrichtung verringert wird.The method according to the invention, on the other hand, envisages the use of Wings before, which themselves are made of resilient material and by bending around the wing longitudinal axis change their angle of attack. The bend is made by the wind pressure acting on the wings, so that the projection with increasing wind pressure the wing area is reduced in the direction of the wind.

Der Vorteil dieser Anordnung gegenüber den bekannten Arten der Flügelverdrehung besteht darin, daß die Regelung unter kleinstem Materialaufwand erfolgt und daß an keiner Stelle Spielraum durch Übertragungsorgane und Schwerpunktstörungen auftreten können, da die Flügel einseitig an mit der Nabe fest verbundenen Holmen angeordnet sind.The advantage of this arrangement over the known types of wing rotation consists in the fact that the regulation takes place with the smallest possible expenditure of material and that At no point there is room for maneuver through transmission organs and focal point disturbances can, as the wings are arranged on one side on spars that are firmly connected to the hub are.
