Abstract

Cette invention se rapporte à des systèmes de dégrivrage à chauffage électrique pour des pièces rotatives d'aéroplanes. Cette invention concerne essentiellement un système de dégivrage thermique, lequel comprend des éléments de chauffage électrique intégrés dans une partie des éléments rotatifs, et auxquels est connecté un générateur synchrone monophasé. Le rotor de ce générateur est disposé avec ses enroulements d'induction dans le même arbre que les éléments rotatifs, tandis que le stator comportant les enroulements d'excitation est monté de manière fixe. L'enroulement d'excitation est relié à une source d'alimentation par l'intermédiaire d'une unité de commande et d'une unité d'affichage du mode de fonctionnement.
