Abstract: An electronic brake system is provided comprising a brake control unit (BCU), an electronic brake actuation controller (EBAC) electrically coupled to the BCU, and an electronic brake actuator (EBA) electrically coupled to the EBAC. The EBAC is configured to detect the EBA based on an electric signal from the EBA. A method of detecting an EBA is also provided. The method comprises the steps of measuring a voltage on an input pin connected to an EBAC, determining an EBA type connected to the input pin based on the voltage, and activating circuitry and software in an EBAC corresponding to the EBA type.

Abstract: The present disclosure provides a skid control system that includes a brake control device configured to convert a current command value to create a braking pressure, wherein the braking pressure is applied to a hydraulically actuated brake and/or an electrically actuated brake. A deceleration control unit receives a filtered wheel speed value and/or a filtered wheel acceleration value from the wheel assembly. A brake control algorithm unit retrieves a noise threshold value corresponding with the at least one of the filtered wheel speed value or the filtered wheel acceleration value. A pressure control unit receives a feedback pressure from the hydraulically actuated brake and/or an electrically actuated brake, wherein the pressure control unit either increases or decreases the current command value in response to a difference between the pressure command value and a feedback pressure being either less than or greater than the noise threshold value.

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: Methods for testing the operation of an aircraft braking system utilize the steps of applying a predetermined electrical energy level to an electromechanical actuator attached to a brake assembly, followed by discontinuing electrical energy to the electromechanical actuator. In some test methods, an actuation level of the electromechanical actuator is determined and used to evaluate braking performance. In other tests, a voltage generated by an electric motor in an actuator is measured and used to evaluate braking performance.

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.
