Abstract
The invention relates to a device () for controlling the setting of the blades () of a rotor () of a propeller, including a radial shaft (), the rotation of which modifies the setting of the blade (), a main spring (), a first end () of which is connected to the rotor () and a second end () of which is connected to a part () 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 () that is orthogonal to the axial direction (), 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.
