Abstract
The invention relates to an aircraft braking system having brakes with electromechanical braking actuators (103) adapted to press selectively against associated stacks of disks in order to generate a braking torque on associated wheels of the aircraft; at least one control module (130) receiving braking setpoints and responding by generating a braking command (121); and at least one power module (120) responding to the braking command by delivering AC power to the motors of actuators connected to the power module so that the motors develop a braking force corresponding to the braking setpoints. According to the invention, the control module includes a digital processor stage (131) and an analog processor unit (135).
Claims4
An aircraft braking system comprising:
- a plurality of brakes with electromechanical braking actuators (3), each one of said electromechanical braking actuators (3) being adapted to press selectively against associated stacks of disks in order to generate a braking torque on associated wheels of the aircraft;
- at least one control module (30;
- 130;
- 230) configured for receiving braking setpoints and responding by generating a braking command (21;
- 121;
- 221);
- and
- at least one power module (20;
- 120;
- 220) configured for responding to the braking command by delivering AC power to the motors of actuators connected to the at least one power module so that said actuators develop braking forces;
- the system being characterized in that the control module comprises:
- a digital processor stage (21;
- 131;
- 231) comprising at least one digital processor unit (33;
- 133;
- 233) configured for:
- receiving digital braking setpoints from at least one digital communications bus;
- implementing complex relationships for controlling the actuators to generate a first braking command in response to the digital braking setpoints (6;
- 106;
- 206);
- and
- an analog processor stage (35;
- 235) comprising at least one programmable logic circuit (37;
- 137;
- 237) for at least
- receiving analog or discrete braking setpoints (9;
- 109;
- 209), and deducing therefrom a second braking command (38;
- 138;
- 238) by implementing simple relationships for controlling the actuators;
- the control module (30;
- 130;
- 230) being further configured for selecting one of the first and second braking commands in response to an external selection order in order to send the selected command to the power module.
