<p>The pitch control mechanism consists of a pitch lever (5) connected by an arm (6) to a plate (8) which turns together with the rotor mast (2), and a fixed plate (11) which is axially slewable along the mast and can incline in any direction relative to it when operated by flight controls (15). The mechanism has an auxiliary plate (24) which is can turn together with the rotary plate and rotate with a given eccentricity relative to the fixed plate. An articulated coupling (16) connects each rotor blade (4) to the auxiliary plate and the fixed plate via a control lever (22) and arm (17) respectively, so that a rotation of the auxiliary plate causes the rotor blade to turn one way or the other about its lengthwise axis (x - x).</p> |
