Rotor blade coupling device and rotor head for rotorcraft.

摘要

In a rotor blade coupling apparatus (2) for coupling to a rotor mast (9) to form a rotor head (1) of a rotorcraft, in particular a helicopter or helicopter, comprising a rotor head central piece (7), at least two on Rotorkopfzentralstück (7) attached to the rotor blade mounts (4) for receiving at least two in a rotor plane (RE) lying rotor blades (3), and at least one connecting means between adjacent rotor blade mounts (4), to a simplified structure of the rotor blade coupling apparatus (2) can be achieved, and the rotor blade coupling apparatus (2) to allow an agile control , This is achieved in that the rotor blade coupling apparatus (2) as the connecting means comprises at least one closed ring (10), said ring (10) arranged at least all rotor blade mounts (4), crossing in each case at least one connection location and all the rotor blade mounts (4) together indirectly connecting is.
