<p>The mechanism consists of a pitch control lever (5) pivoted to an arm (6) connected to a plate (8) which turns together with the rotor mast (2), and a cyclic plate system in which the plate rotates on a fixed plate (10) which can slide along the mast and incline in any direction relative to it by means of flight control actuators (14). The mechanism has a secondary rotary plate (23) which turns together with the mast and moves axially with the fixed plate (10) but does not incline relative to the mast. Each rotor blade has an articulated coupling (16) with two levers (17,18) and four articulated joints (19 - 22). The two levers can turn relative to one another about one of the joints (19); the first lever is able to turn about a second joint (20) connected to the secondary plate, and the second lever (18) turns relative to the pitch lever.</p> |
