Abstract: A method for detecting an erroneous velocity data using a controller in communication with a velocity sensor onboard a vehicle includes receiving a time-series velocity data from the velocity sensor, calculating a time-series acceleration data using the time-series velocity data, calculating a time-series jerk data using the time-series acceleration data, calculating a saturated (numerically bounded) jerk data using the time-series jerk data, calculating an estimated acceleration data using the saturated jerk data, calculating a difference between the estimated acceleration data and the time-series acceleration data, and determining whether the difference is greater than a threshold value. The erroneous velocity data is detected in response to the difference being greater than the threshold value.

Abstract: An autobrake system includes a brake control unit (BCU), and a control knob in electronic communication with the BCU. The BCU is configured to receive a position signal from the control knob, the position signal corresponding a position of the control knob. The BCU is configured to select a braking deceleration based upon the position signal, wherein the braking deceleration continuously changes between a minimum braking deceleration and a maximum deceleration in response to the control knob moving between a first position and a second position for fine tuning of the braking deceleration.

Abstract: The present disclosure provides an actuator assembly having a ball nut comprising a helical track and a ball screw. The ball screw of the actuator assembly includes a first translation bearing track having a first diameter, wherein the helical track and the first translation bearing track form a first translation bearing raceway in which a first translation bearing ball is disposed. The ball screw further includes a second translation bearing track having a second diameter, wherein the helical track and the second translation bearing track form a second translation bearing raceway in which a second translation bearing ball is disposed. The first diameter and the second diameter are not equal.

Abstract: Braking control systems and methods, such as for an aircraft, use a dump valve to rapidly decrease hydraulic pressure applied to a brake actuator during a wheel skid condition. In response to the wheel speed recovering, the dump valve is commanded closed and the brake control system returns to normal braking. The dump valve and a servo-valve may work harmoniously for locked wheel brake control.

Abstract: A method of performing prognostics on a hydraulic brake system of an aircraft may include determining, during primary braking mode and by a hydraulic brake controller, a first status of a first brake pressure sensor adjacent a brake assembly. The method may also include, in response to determining that the first status of the first brake pressure sensor is valid, determining, during park braking mode and by the hydraulic brake controller, a second status of a second brake pressure sensor adjacent a park valve assembly. In response to determining that the first status of the first brake pressure sensor is degraded, the method may include outputting, by the hydraulic brake controller, at least one of an inspection indicator and a maintenance indicator.

Abstract: Systems and methods for detecting runway conditions 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 weight on wheel time limit may be reached prior to the axle reference speeds reaching an on ground threshold. A brake control unit may determine that the runway is contaminated if the on ground threshold was not reached.

Abstract: A method for controlling brakes is provided. The method comprises detecting an imminent skid by an anti-skid controller/deceleration controller (ASK/DK). The ASK/DK outputs at least one of a negative desired pressure command to a pressure control unit (PK) in response to detecting the imminent skid and causes a current command output from the PK to be reduced to release braking pressure if the negative desired pressure command minus a measured feedback pressure is greater than a deadband of the PK or outputs a negative desired force command to a force control unit (ForK) in response to detecting the imminent skid and causing a current command output from the ForK to be reduced to release braking force if the negative desired force command minus a measured feedback force is greater than a deadband of the Fork. A brake control system is also provided.
