Patent ID: 7369922

Claim:
A system architecture for managing aircraft landing gear and suitable for performing at least one of the functions selected from: retracting/extending retractable undercarriages by means of retraction/extension actuators and retraction/extension information coming from associated sensors; steering steerable wheels carried by at least one of the undercarriages by means of steering actuators and steering information coming from associated sensors; the architecture being suitable also for braking braked wheels carried by at least one of the undercarriages by means of braking actuators and braking information coming from associated sensors; the architecture comprising at least one communications network having connected thereto: at least a fraction of the retraction/extension actuators, and/or of the steering actuators, and the sensors associated with said actuators; and one or more control units suitable for controlling the retraction/extension actuators and/or the steering actuators connected to the communications network as a function of information delivered by the associated sensors; wherein at least a fraction of the braking actuators and the sensors associated with said actuators are connected to the communications network, the control unit(s) being adapted to control the braking actuators connected to the communications network as a function of information delivered by the associated sensors, the communications network having transmission characteristics adapted to enabling the control unit(s) to implement antilock servo-control for controlling the braking actuators.
