Abstract
A variable-pitch vane including a plurality of propeller blades (). Each blade has a variable pitch according to a blade rotational axis (A) and a root (). A plurality of rotor connecting shafts (), each shaft having a foot () and a head (). The root () of each blade is mounted on the head () of a rotor connecting shaft via a pivot () in such a way as to allow each blade () to rotate according to the blade rotational axis (A), in which each blade () has a blade pitch, such that the blade rotational axis (A) is inclined relative to a radial axis (A) passing through the foot () of the corresponding shaft.
