Abstract

L'invention concerne un système de servo-commande à deux canaux pour pilote automatique. Ledit système comporte un servo-moteur dans chaque canal produisant un mouvement identique de sortie en réponse à un signal de commande. Des tachymètres délivrent des signaux proportionnels à la vitesse des servo-moteurs respectifs. Un différentiel alimenté par les servo-moteurs est accouplé à la gouverne et commande un dispositif de réaction délivrant des signaux aux canaux respectifs pour permettre de détecter une panne éventuelle de l'un de ces derniers. Un dispositif de surveillance interrompt le fonctionnement du canal défaillant. Application au pilotage automatique d'engins aériens.
