Abstract
The method for reducing aircraft carbon brake wear involves monitoring the commanded initiation of braking, and setting a residual brake clamping force to a predetermined minimum residual brake clamping force, which is maintained following the commanded initiation of braking to prevent release of braking during taxiing of the aircraft. The minimum residual brake clamping force is applied despite a commanded release of braking until at least one predetermined control logic condition occurs.
Claims25
A method for controlling carbon brakes of an aircraft having a plurality of wheels and a corresponding plurality of wheel brakes for the plurality of wheels to reduce brake wear when the aircraft is taxiing, comprising the steps of:
- monitoring commanded initiation of braking of any of the plurality of wheel brakes of the aircraft;
- setting a residual brake clamping force to a predetermined minimum residual brake clamping force for the plurality of wheel brakes in response to said commanded initiation of braking of any of the plurality of wheel brakes;
- and
- applying said predetermined minimum residual brake clamping force to the plurality of wheel brakes despite a commanded release of braking of any of the plurality of wheel brakes.
A method for controlling carbon brakes of an aircraft having a plurality of wheels and a corresponding plurality of wheel brakes for the plurality of wheels to reduce brake wear when the aircraft is taxiing, comprising the steps of:
- monitoring commanded initiation of braking of any of the plurality of wheel brakes of the aircraft;
- setting a residual brake clamping force to a predetermined minimum residual brake clamping force for the plurality of wheel brakes in response to said commanded initiation of braking of any of the plurality of wheel brakes;
- monitoring commanded release of braking of any of the plurality of wheel brakes of the aircraft;
- applying said predetermined minimum residual brake clamping force to the plurality of wheel brakes following said commanded release of braking of any of the plurality of wheel brakes until at least one predetermined control logic condition occurs;
- and
- setting said residual drag brake clamping force to zero in response to said at least one control logic condition.
A system for controlling carbon brakes of an aircraft having a plurality of wheels and a corresponding plurality of wheel brakes for the plurality of wheels to reduce brake wear when the aircraft is taxiing, the system comprising:
- means for monitoring commanded initiation of braking of any of the plurality of wheel brakes of the aircraft;
- means for setting a residual brake clamping force to a predetermined minimum residual brake clamping force for the plurality of wheel brakes in response to the commanded initiation of braking of any of the plurality of wheel brakes;
- and
- means for applying the predetermined minimum residual brake clamping force to the plurality of wheel brakes despite a commanded release of braking of any of the plurality of wheel brakes.
