CA 2665625
A system (100) and method for switching power sources for an aircraft electric brake system is disclosed. The method removes battery power from electric brake actuator controls (110,112,118,120,152,154,160,162) during flight until landing gear extension occurs. The method utilizes a logic circuit (116,124,158,166) to switch between available power sources (112,120,128,154,162) based on a plurality of control signals. The method minimizes the total power drawn during flight, and saves battery power if the aircraft calls for operating on battery power only.
L'invention concerne un système et un procédé pour commuter les sources de courant d'un système de frein électrique d'avion. Le procédé supprime le courant de batterie des commandes d'actionneur de frein électrique pendant le vol jusqu'à la sortie du train d'atterrissage. Le procédé utilise un circuit logique pour commuter entre des sources de courant disponibles sur la base d'une pluralité de signaux de commande. Le procédé diminue la puissance totale utilisée pendant le vol et économise du courant de la batterie pour utilisation possible si l'avion requiert de ne fonctionner que sur courant de batterie.
