  • Publication number: 20230373450
    Abstract: A wheel-braking system architecture for an aircraft is provided. The architecture includes a friction brake; an electromechanical actuator associated with a power module connected to a digital communication module by a first driver module; and a controller having both a power supply unit for powering the power module by delivering a power supply voltage (Vc) thereto, and also a control unit connected to the digital communication unit in order to transmit a digital control signal to the digital communication module. The control unit can be connected to the driver unit by an analog wired connection in order to transmit that to a first analog braking order from which the first driver module drives the power module to produce a degraded power supply current for the actuator.
