Abstract

Système de freinage (1) pour un aéronef comprenant au moins un dispositif à actionnement électrique (2) configuré pour remplir au moins une cavité (3L, 3R) d’un frein de l’aéronef par un fluide hydraulique (Fs), ledit dispositif à actionnement électrique (2) présentant un mode de fonctionnement bi-stable, et un mode de fonctionnement progressif, et au moins un premier organe de commande (4) du dispositif à actionnement électrique (2), caractérisé en ce que le système de freinage comprend au moins un deuxième organe de commande (5) du dispositif à actionnement électrique (2), le premier organe de commande (4) générant un ordre de parc (Co/f) qui active le mode de fonctionnement bi-stable, et le deuxième organe de commande (5) générant un ordre de freinage secours (Cv) qui active le mode de fonctionnement progressif, l’au moins un premier organe de commande (4) étant indépendant de l’au moins un deuxième organe de commande (5). Figure 1A braking system (1) for an aircraft comprising at least one electrically actuated device (2) configured to fill at least one cavity (3L, 3R) of an aircraft brake with a hydraulic fluid (Fs), said electrically actuated device (2) having a bistable operating mode and a progressive operating mode, and at least one first control element (4) of the electrically actuated device (2), characterized in that the braking system comprises at least one second control element (5) of the electrically actuated device (2), the first control element (4) generating a park command (Co/f) that activates the bistable operating mode, and the second control element (5) generating an emergency braking command (Cv) that activates the progressive operating mode, the at least one first control element (4) being independent of the at least one second control element (5).
