Definitions

  • the rotor 2 is also mounted on a mast 6 of the aircraft 1 so as to be rotatable about an axis of rotation 5.
  • the fact that the rotor 2 of the gyroplane can be set into autorotation means that it is not driven by a drive of the gyroplane 1 during a normal flight phase.
  • the rotor 2 is set into rotation during flight by a headwind flowing in from the front, namely autorotation. This means that, for example, a torque-compensating tail rotor can be dispensed with.
  • the autorotation ensures a very high level of flight safety, since the rotor 2 is constantly in autorotation.
  • the rotor blade bearing 16 again comprises the two joint elements 29, 30, which are articulated, by means of the joints 39 - 42, to the carrier element 23 and/or are connected to the rotor 2 or the rotor blades 3, 4, as already described in the previous figures. This allows the rotor 2 to beat about the beat axis 17, with the rotor's center of gravity 20 remaining in the rotation axis 5.

Abstract

L'invention concerne un aéronef, de préférence un aéronef à voilure tournante (1), en particulier un gyrocoptère, un hélicoptère ou un multicoptère, et/ou un avion convertible à rotor basculant, comprenant au moins un rotor (2), qui comprend au moins deux pales de rotor (3, 4), et au moins une tête de rotor (15) qui peut tourner autour d'un axe de rotation (5) et, pour recevoir les pales de rotor (3, 4), comporte au moins un palier de pale de rotor (16), au moyen duquel les pales de rotor (3, 4) peuvent battre autour d'au moins un axe de battement (17) de telle sorte qu'un centre de gravité (20) du rotor (2) reste dans la région de l'axe de rotation (5). Selon l'invention, le palier de pale de rotor (16) est disposé à l'extérieur de l'axe de battement (17).
