Description

Die Erfindung bezieht sich auf eine Schlagflügelwindkraftmaschine mit um die Flügellängsachse schwingendem Flügel und einem um parallel zur Flügelachse an deren Ende befindlichen Gelenken schwingendem Ruder.The invention relates to a flapping wing wind power machine with a wing swinging around the longitudinal axis of the wing and a wing that is parallel to the wing axis the ends of which are located joints swinging rudder.

Es sind Schlagwindflügelkraftmaschinen bekannt, bei denen jeweils die Umsteuerung des Ruders über Steuermittel, wie Gestänge oder Federn, erfolgt. Diese Zwangsumsteuerung verbraucht Energie und funktioniert vor allem bei niedrigen Windgeschwindigkeiten nicht, solche Anlagen bleiben dann stehen.There are flapping vane power machines known in which the rudder is reversed Control means, such as linkage or springs, takes place. This forced reversal consumes energy and works especially not at low wind speeds, such systems then come to a standstill.

Die Aufgabe, die der Erfindung zugrundeliegt, besteht darin, eine Schlagflügelwindkraftmaschine mit höherer Leistung zu schaffen, die vor allem auch störungsfrei funktioniert und auch bei geringer Windgeschwindigkeit nicht zum Stillstand kommt.The object on which the invention is based exists in creating a flapping wing wind power machine with higher performance that, above all, is trouble-free works and does not come to a standstill even at low wind speeds.

Die Lösung dieser Aufgabe besteht darin, daß das Ruder frei schwingend angebracht ist.The solution to this problem is that the rudder is mounted swinging freely.

Zur Weiterbildung können mehrere Schlagflügel in bestimmtem Winkel hintereinander aufgestellt werden, um die induzierte Frequenz auszunützen.For further training, several flapping wings can be set up one behind the other at a certain angle, to take advantage of the induced frequency.

In der Zeichnung ist die Schlagflügelwindkraftmaschine schematisch in drei Phasen des Funktionsabiaufes dargestelltIn the drawing is the flapping wing wind power machine shown schematically in three phases of the functional sequence

In A b b. 1 sind die Anströmung der Schlagflügelwindkraftmaschine und die Druckverhältnisse gezeigtIn A b b. 1 shows the flow to the flapping wing wind power machine and the pressure conditions

In A b b. 2 haben die Druckverhältnisse dazu geführt, daß sich das Ruder B und der Flügel A unter Abgabe von Energie im Drehpunkt Ox in die Zone des Unterdrucks bewegt haben, bis die Strömung abreißtIn A b b. 2, the pressure conditions have caused the rudder B and the wing A to move into the zone of negative pressure, releasing energy at the pivot point Ox, until the flow stops

In A b b. 3 ist die entgegengesetzte Phase dargestellt Die Druckverhältnisse haben sich entgegengesetzt verändertIn A b b. 3 shows the opposite phase The pressure conditions have changed in the opposite direction
