Description

I'Nabe für mechanisch angetriebene Hubschrauber" Die Erfindung betrifft eine Nabe für hechanisch angetriebene Hubschrauber, die gewalzte bzw. aus Blech bestehende Verbindungs- oder Zugstangen besitzt. Die Erfindung wird beispielsweise an Hand beiliegender-Zeichnungen erläutert, worins Fig. 1 eine Vorderansicht der Nabe ist und Fig. 2 eine perspektivische Ansicht der Nabe ist."Hub for mechanically driven helicopters" The invention relates to a hub for mechanically driven helicopters, which has connecting rods or tie rods that are rolled or made of sheet metal. The invention is explained, for example, with reference to the accompanying drawings, in which FIG. 1 is a front view of the hub and FIG. 2 is a perspective view of the hub.

Wie aus der Zeichnung hervorgehtg ist die Nabe "gemäss der Erfindung im wesentlichen aus gewalzten bzw. aus Blech gebildeten Zug- oder Verbindungsstangen 4 gebildet, die mit den Befestigungen für die Rotorblätter 1 und den Zentralmuffen 3 verbunden sind, die senkrecht zu den Achsen der erwähnte Zug-oder Verbindungsstangen und zu einem Träger 2 für dieselben für die Steigungsregelung angeordnet sind.As can be seen from the drawing, the hub "according to the invention is essentially formed from rolled or sheet metal pull or connecting rods 4, which are connected to the fastenings for the rotor blades 1 and the central sleeves 3, which are perpendicular to the axes of the aforementioned Pull or connecting rods and to a carrier 2 for the same for the incline control are arranged.

Da der Hubschrauber mechanisch angetrieben wird, entstehen, wie aus Fig. 2 ersichtli-ch ist, Beanspruchungen infolge des Drehmoments des Rotorsg die die Verwendung von Verbindungsstangen aus Blech 4 in Frage stellen, die aus Bandstahlpaketen bestehen; die Beanspruchungen werden aber von den erwähnten Zentralmuffen aufgenommen.Since the helicopter is powered mechanically, how out of Fig. 2 shows the stresses due to the torque of the rotor question the use of connecting rods made of sheet metal 4, those made of strip steel packages exist; however, the loads are absorbed by the aforementioned central sleeves.

Diese Lösung gestattet es also erstmalig, die Vorteile von gewalzten bzw. aus Blech oder Bandstahl bestehenden Verbindungs-oder Zugstangen, wie sie bereits für Hubschrauber mit Düsentriebwerk angewendet werdeng bei mechanisch angetriebenen Hubschraubern zu erreichen.This solution allows for the first time the advantages of rolled or connecting rods or tie rods made of sheet metal or strip steel, as they are already for helicopters with jet engines are used for mechanically powered Helicopters to reach.
