Pitch control swash plate assembly of a main rotor as well as a rotor with such an assembly

摘要

The assembly (10) has a non-rotary swashplate (12) retained against rotation about a rotational axis (AX) and a rotary swashplate (11) rotating around the rotational axis. A drive unit (100) connects the rotary swashplate and a rotor mast (2) of a main rotor (1) in rotation around the axis. An annular linear connection unit (200) is integrated to the rotary swashplate. A drive arm has an end (110) connected to the rotary swashplate by the annular linear connection unit and another end (120) connected to the rotor mast by a slideway connection unit of the drive unit. An independent claim is also included a rotor of a rotorcraft with a rotor mast rotationally driving blades around a rotational axis.
