system for varying the incidence of blades of an aircraft turboprop machine, propeller for aircraft turbocharger, aircraft turbocharger, and process of commanding the incidence of blades for an aircraft turbocharger propeller

摘要

A system for varying an angle of attack of blades of an aircraft turbine engine propeller, including an axial flow brushless motor including a stator including coils, and a rotor including permanent magnets. The rotor is mounted axially movable between a locked position in which it is secured in rotation with a rotary hub of the propeller, and an unlocked position in which its rotation relative to the hub along the axis of rotation of the propeller causes a variation of the angle of attack of the blades via a mechanical connecting mechanism.
