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: An aircraft includes a brake lever for receiving a pilot braking input as a lever travel of the brake lever, a braking wheel operatively coupled with the brake lever to brake the aircraft based on the lever travel, a brake actuator operatively coupled with the braking wheel to apply a braking force in response to a braking pressure provided to the brake actuator, and a brake pressure circuit. The brake pressure circuit is configured for: estimating a maximum braking pressure above which the braking wheel will skid with respect to a ground surface; scaling a lever gain of the brake lever to command the maximum braking pressure at a full travel of the brake lever such that a remaining brake lever travel indicates the amount of braking capability remaining for the aircraft; and braking the braking wheel based on the lever gain and the lever travel.

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: A method of determining the integrity of an electric or hydraulic braking control system. A reduction rate of a voltage or hydraulic pressure in the braking control system is determined, and the integrity of the braking control system is determined by comparing the reduction rate with a threshold. The braking control system may be an aircraft braking control system, and the method may be performed during flight of the aircraft—typically during cruise.

摘要: A method of braking left and right landing gear wheels on respective left and right sides of an aircraft. A desired left braking parameter (L) is received for the left wheel and a desired right braking parameter (R) is received for the right wheel. The left wheel is braked with a reduced left braking parameter (L′) which is less than the desired left braking parameter (L), and the right wheel is braked with a reduced right braking parameter (R′) which is less than the desired right braking parameter (R). A difference between the braking parameters is maintained so that L′−R′=L−R.

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.

摘要: A method for fault detection and accommodation for a controller and actuator system is provided. The method includes receiving, from a controller, a flag at an actuator in response to an excitation voltage and current falling below a threshold value, engaging a sensor in the actuator in response to receiving the flag, receiving, using the sensor a first load cell signal and a second load cell signal in response to the sensor being engaged, determining how actuator is operating brake based on the received flag, first load cell signal, and second load cell signal, adjusting a state of the actuator based on the determination, and reporting the state of the actuator by transmitting a report signal to the controller.
