Description

Gegenstand der Erfindung ist ein gegenläufiges Rotorgetriebe auf einer angetriebenen Welle.The invention is an opposing rotor gear on a driven shaft.

Dieses Prinzip ist universell anwendbar, z. B. in den Bereichen Hubschraubertechnik (Rotoren), Schiffsantrieb (Schraube) und Flugzeugantrieb (Propeller).This principle is universally applicable, for. As in the areas of helicopter technology (rotors), marine propulsion (screw) and aircraft propulsion (propeller).

Im Beispiel wird das Prinzip anhand der Hubschraubertechnik erläutert.In the example, the principle is explained by means of helicopter technology.

Es unterscheidet sich gegenüber der bekannten Koaxialhubschraubertechnik darin, dass keine Hohlwelle benötigt wird.It differs from the known Koaxialhubschraubertechnik in that no hollow shaft is needed.

Auf einer angetriebenen Welle können zwei oder mehrere übereinander in der Drehzahl unterschiedliche Koaxialrotoren gegenläufig angetrieben werden.On a driven shaft, two or more coaxial rotors different in speed can be driven in opposite directions.

Drehbar und in alle Richtungen neigbar entsteht ein revolutionärer Starrflügler-Gelenk-Koaxialhubschrauber.Rotatable and tiltable in all directions, a revolutionary fixed-wing aircraft coaxial helicopter is created.

Der Motor und die Personen hängen an diesem Koaxialrotorgetriebe, verbunden mit einem Kreuzgelenk können über Gewichtsverlagerung und Verdrehung noch nie dagewesene Flugmanöver ausgeübt werden. Unter Verwendung eines Außenrings werden Luftverwirbelungen weitgehend vermieden und die Rotorblätter geschützt.The motor and the people hang on this coaxial rotor gear, connected to a universal joint can be exercised over weight shifting and twisting unprecedented maneuvers. Using an outer ring, air turbulence is largely avoided and the rotor blades are protected.

Wenig Technik, einfachste Bedienung, revolutionäre Flugeigenschaften und geringe Produktionskosten unterscheiden diese Erfindung von herkömmlichen Hubschraubern.Little technology, ease of use, revolutionary flight characteristics and low production costs distinguish this invention from conventional helicopters.

Ein Ausführungsbeispiel der Erfindung wird anhand von Zeichnung und Figuren erläutert.An embodiment of the invention will be explained with reference to drawings and figures.
