<p>The invention relates to a device (1) for controlling the setting of the blades (2) of a rotor (3) of a propeller, including a radial shaft (6), the rotation of which modifies the setting of the blade (2), a main spring (13), a first end (14) of which is connected to the rotor (3) and a second end (15) of which is connected to a part (8, 10) having an axial movement which drives the rotation of the radial shaft, and has a movement, the travel of which is offset relative to the first end in a direction (7) that is orthogonal to the axial direction (5), the main spring exerting a resilient force which aims to move the parts toward a position in which the cord of the profile of the blade is orthogonal to the plane of rotation of the propeller, in the absence of part control by means of a jack.</p> |
