Abstract
The rotating plate of the system is fixed in rotation with the rotor by a driver with two rigid driving tracks extending axially and diametrically opposite in being fixed in rotation with the rotor. Each track engages with one of two driving fingers fixed in rotation with the rotating plate and diametrically opposite on this latter. Each track has two webs between which one finger is engaged with the result of following on this track a rectilinear trajectory, parallel to the rotor axis and a circular arc trajectory centerd on this axis, respectively in the case of change of collective and cyclic pitch.
