Abstract

Cette invention se rapporte au domaine de l'aéronautique et son résultat technique consiste en une meilleure précision dans la mesure des angles courants de calage des pales. Ce résultat consiste également en une plus grande fiabilité du fonctionnement du système, ceci grâce à des dispositifs de protection contre les écarts incontrôlables de l'hélice à des angles élevés de calage des pales, et à l'aide d'un signal indiquant la position courante des pales. A cette fin, le système de commande de l'hélice à pas variable et à retour d'asservissement se présente sous forme d'un tube bêta (6) se trouvant en coopération avec un capteur (7) de la position angulaire des pales (2). Ce système comprend une unité de commande électronique (32), un convertisseur électro-hydraulique (33), un limiteur hydromécanique à maximum de fréquence (34), ainsi que des canaux de commande de l'hélice comportant un élément de régulation qui se présente sous forme, par exemple, de clapets à tiroir. Ce système se caractérise par la liaison mécanique, dans le sens axial, du corps (16) du capteur (7) au corps (1) de l'hélice ou à l'arbre d'entraînement de l'hélice par une unité de type palier (25). Ce système se caractérise en outre par le fait que les canaux de commande comportent un clapet à tiroir (40) qui est actionné par un clapet électromagnétique (41) et qui permet de passer d'un mode de commande par l'unité électronique en un mode de commande par le limiteur hydromécanique à maximum de fréquence de rotation. L'électro-aimant (41), enfin, est connecté électriquement au capteur de position angulaire des pales par l'intermédiaire de l'unité de commande électronique.
