  • Architecture for an airplane braking system including two computers and capable of withstanding two breakdowns, and a method of managing such an architecture
    Patent number: 7401869
    Abstract: The invention relates to an architecture for a braking system for an airplane fitted with a plurality of undercarriages each carrying a plurality of wheels, at least some of which are fitted with brakes, the architecture comprising at least two braking computers each having two modules such that in each computer, one of the modules controls a first fraction of the brakes and the other module controls a second fraction of the brakes complementary to the first. According to the invention, the architecture is configured to operate in any one of the following modes of operation: a first normal mode in which both modules of one of the braking computers are active for controlling all of the brakes; a second normal mode in which both modules of the other braking computer are active for controlling all of the brakes; and an alternative mode in which one module of one of the braking computers and one module of the other braking computer are active for controlling all of the brakes.
