Abstract (en)
[origin: FR2923210A1] The assembly has a rotor (1) for centering a swash plate with respect to a main rotation axis of the rotor. The rotor has a cylinder rotatably driving a crown-ball joint (4). A roller bearing has a triangular crown (11) freely moved along the axis. The crown-ball joint is connected to levers (25) of shanks of blades (26) by balls (19-21) via tie rods (22-24) such that pitch angle of the blades is cyclically controlled by acting in three points on the crown to control a collective pitch and a yaw in case of a counter-rotating rotor by differentiation of the collective pitch between the rotors.
