Description

Der Monoplan-Rotor ist, unter anderem, vom Flügel der Lindensamen abgeleitet und besteht aus einem flachen, asymetrischen, elastischem Blatt mit entgegengesetzt gewölbten/verdrehten Blattseiten (Zeichnung 1) wobei das Verhältnis der kürzeren zur längeren Blattseite ca. 1:1,23 beträgt, von der Achse (1/4 und 2/4) aus gemessen und in nicht gewölbtem Zustand.The Monoplan rotor is, among other things, derived from the wing of the linden seeds and consists of a flat, asymmetric, elastic leaf with opposite curved / twisted leaf sides (drawing 1 ) wherein the ratio of the shorter to the longer leaf side is about 1: 1.23, from the axis ( 1 / 4 and 2 / 4 ) measured out and in a non-curved state.

Der Wölbungswinkel zwischen den beiden Blattseiten ist an der Unterkante oder der Kante der Drehrichtung (1/1 und 2/1) stumpfer als der entsprechende Winkel der Oberkante (1/5).The curvature angle between the two sides of the sheet is at the lower edge or the edge of the direction of rotation ( 1 / 1 and 2 / 1 ) blunt than the corresponding angle of the top edge ( 1 / 5 ).

Die beiden Blattseiten des Monoplan-Rotors werden an der Außenseite durch zwei Seile (2/2) gespannt, die an einem Konus auf Achsenhöhe (2/3) und den nötigen Halterungen auf den beiden Blattseiten befestigt werden. Eine Variante dazu sind zwei entsprechende Streben, die das Blatt von der Rückseite (dem Wind abgewandte Seite) abstützen und spannen.The two leaf sides of the monoplane rotor are on the outside by two ropes ( 2 / 2 ), which are attached to a cone at axis height ( 2 / 3 ) and the necessary brackets are attached to the two sides of the sheet. A variant of this are two corresponding struts, which support the sheet from the back (the wind side facing away) and tension.

1 zeigt den Grundriß. 2 zeigt die schematische Seitenansicht des gespannten Rotors. 1 shows the floor plan. 2 shows the schematic side view of the tensioned rotor.

1/6 und 2/6 zeigen abgewinkelte Blattspitzen. 1 / 6 and 2 / 6 show angled leaf tips.

1/7 zeigt die Linie an der die beiden Blattseiten abgewinkelt werden. 1 / 7 shows the line at which the two sides of the sheet are angled.
