    摘要: A system and method are provided for continuous monitoring and controlling of aircraft braking that can reduce brake wear and aircraft operating costs through the retention of carbon brake powder from the brakes or addition of carbon powder in a device mounted with respect to the brake disk stack. The use of carbon powder reduces brake wear by providing small particles between the brake disks, acting as a buffer between the brake disks when the brake stack is clamped together. Moreover, when carbon powder or small particles are used at application, such use reduces the roughness of the carbon surface and reduces the number of large particles from braking off the carbon surface, thereby reducing brake wear. Adaptive or selective braking may be used in conjunction with carbon powder to further reduce carbon brake wear.

    摘要: A braking system for an aircraft may comprise: a brake assembly including a brake stack; an electric braking subsystem having an electric brake actuator configured to operate the brake assembly; and a controller in operable communication with the electric braking subsystem, the controller configured to perform a wear depth measurement process, the wear depth measurement process comprising: determine a reference position of the electric brake actuator; command the electric brake actuator to extend toward the brake stack; receive a force measurement from a load cell in response to the electric brake actuator contacting the brake stack; determine a linear travel distance of the electric brake actuator based on an end position determined from the force measurement; and determine a wear depth based on calculating a difference between the linear travel distance and a prior linear travel distance of the electric brake actuator.

    摘要: Systems and methods for aircraft autobraking are disclosed. The systems and methods may allow for autobraking in both manned and autonomous aircrafts, and may assist in maintaining a desired course during autobraking. The systems and methods may include an aircraft control mode executive module configured to receive manual and/or autonomous brake signal inputs and deceleration signal inputs. The systems and methods may also include various modules configured to aid in calculating, transmitting, and executing pedal brake commands on a braking system, such as, an autobrake controller, a pedal balance controller, an autobrake pedal executive module, a pedal executive module, and/or a pedal braking controller.

    摘要: 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.
