Abstract: A system for two-stage determination of a brakefail of an aircraft brake system includes an aircraft brake. The aircraft brake is configured to receive a current command value, convert the current command value to a braking pressure and output a detected pressure value corresponding to the braking pressure. The system also includes a brake control unit (BCU) configured to determine a pressure command value, convert the pressure command value to the current command value and to determine whether a brakefail event has occurred based on the pressure command value, the current command value and the detected pressure value.

Abstract: A system for determining a deceleration rate of an aircraft, in various embodiments, includes at least one component capable of transmitting a first deceleration rate. The system also includes a brake control unit coupled to the at least one component and having a brake controller that is configured to receive the first deceleration rate from the at least one component and to determine a likely accurate deceleration rate based on the first deceleration rate, a second deceleration rate and a hierarchy of sources of deceleration rates.

Abstract: The present disclosure relates to load cell gain compensation, and more particularly, to a system that compensates for the effect of parasitic resistances on the behavior of brakes having load cells. The load cell gain compensation may be in response to an error representing the ratio of an instantaneous current to an expected current. In various embodiments, the gain compensation may enhance brake component performance.

Abstract: Systems and methods for detecting an on ground condition of an aircraft are disclosed. A weight on wheel system may determine that an aircraft is on the ground. Wheel speed sensors may measure the speed of the aircraft wheels. Axle reference speeds may be calculated for each landing gear based on the speed of the aircraft wheels. A brake control unit may determine that the axle reference speed for each axle of the landing gears is above an on ground threshold speed, and the brake control unit may allow braking to be applied.

Abstract: A brake control system includes a servo valve and a brake control unit in electronic communication with the servo valve. The servo valve is configured to receive a hydraulic fluid and provide the hydraulic fluid to apply braking force to a wheel via a hydraulic line. The brake control unit is configured to calibrate the servo valve and determine whether a calibration of the servo valve was successful. In response to the calibration of the servo valve being successful, the brake control unit can operate the servo valve in an open-loop system. In response to the calibration of the servo valve being unsuccessful, the brake control unit can operate the servo valve in a closed-loop system.

Abstract: A brake control system of the present disclosure calibrates a servo valve and calculates a calibrated transfer function associated with the servo valve for precise braking in open-loop mode. The calibration steps may include determining i) whether an aircraft is on a ground surface, ii) whether the aircraft is not moving relative to the ground surface, and iii) whether braking is applied to a brake system of the aircraft. The brake control unit may calibrate the servo valve in response to the brake control unit determining that i) the aircraft is on the ground surface, ii) the aircraft is not moving relative to the ground surface, and iii) the braking is not applied to the brake system of the aircraft. The calibration process includes sending two or more test currents to the servo valve, and determining braking pressures associated with those test currents to calculate the transfer function.

Abstract: Systems and methods for shut off valve failure detection are provided. The system may comprise a housing, a shut off valve disposed within the housing, a first servovalve and a second servovalve coupled to the housing, and a pressure sensor disposed within the housing in fluid communication with the shut off valve. A controller may receive a pressure signal from the pressure sensor in the system, and a brake signal from a brake input device. The controller may determine whether there has been a shut off valve failure in the system in response to the pressure signal being greater than a pressure threshold and the controller failing to receive the brake signal, for a threshold period. The controller may then send a signal to a notification system in response to detection of the shut off valve failure and output a shut off valve failure notification.
