Abstract
Régulateur effectuant une intégration des modes de réglage de la poussée principal et secondaire en une unique commande redontante pour réduire la complexité du système. Il comporte un générateur 30 de signal de référence de vitesse de la soufflante et un générateur 44 de signal de référence de rapport des pressions du moteur qui produisent des signaux N1a et EPRa fonction de la poussée demandée qui sont comparés respectivement à la vitesse de la soufflante et au rapport effectif des pressions du moteur par des additionneurs 26, 40 pour produire des signaux d'erreur appliqués à un générateur 50 de paramètre de poussée qui applique au moteur 22 un signal de régulation fonction des deux signaux d'erreur dans le cas où l'un des circuits fonctionne anormalement, le générateur 50 fonctionnant alors uniquement en réponse à l'autre circuit. Application aux moteurs d'avion à réaction.
