OBS

La régulation de puissance par mise en drapeau consiste à obliger les pales à pivoter autour de leur axe mécanique de façon à réduire l’angle d’attaque, donc le Cz et enfin le couple moteur. Cette réduction de l’angle d’attaque est obtenue par augmentation du calage (angle que fait la corde du profil avec le plan de rotation de l’hélice) moyen des pales.
