Abstract
Control lever for the angular setting of a stator blade, comprising a first end intended to be fitted in a fixed manner on a blade pivot, a second end comprising a cylindrical pin for fitting on a control ring, and a flat intermediate part connecting the first and second ends having shapes and dimensions determined in order to increase the natural frequencies of the lever in flexion and in torsion above the vibratory frequencies of the turboshaft engine upstream of the lever and in order to retain the stiffness of the lever.
