Abstract: A variable stator of a turbomachine with a profile skeleton line extending along a meridional flow line, with the stator being radially divided into at least three zones (Z0, Z1, Z2) and with the respective radial inner and the radial outer profile skeleton line of each zone (Z0, Z1, Z2) being designed such that it satisfies the following equations: α * = α 1 - α P α 1 - α 2 S * = S P S where: P is any point of the profile skeleton line, α1 is the angle of inclination at the stator leading edge, α2 is the angle of inclination at the stator trailing edge, α* is the dimensionless, specific angle of the total curvature, S* is the dimensionless, specific extension, αP is the angle of the tangent at any point P of the profile skeleton line to the central meridional flow line, sP is the extension of the profile skeleton line at any point P, and S is the total extension of the profile skeleton line.
