Abstract
L'invention concerne une commande électronique d'un stabilisateur d'hélicoptère, et un fonctionnement à l'épreuve des défaillances des dispositifs de manoeuvre. Le système de l'invention comprend des moyens de manoeuvre 30, 31, des générateurs de commande de position 60, 60a, des moyens sensibles à la position 59, 59a, pour fournir chacun un signal de position réelle lié à la position du moyen de manoeuvre correspondant, des moyens d'entraînement 32, 33, sensibles chacun au moyen de détection de position et au moyen générateur de commande de position correspondants pour fournir un signal au moyen de manoeuvre correspondant en réponse à la différence entre le signal de commande de position et le signal de position réelle de ce moyen de manoeuvre, et un moyen de défaillance 66 pour comparer les signaux de position réelle et engendrer un signal d'alarme en reponse à une disparité supérieure à une valeur de seuil. L'invention s'applique à des hélicoptères à stabilisateur à angle d'incidence variable.
