    摘要: A braking system is provided. The braking system may comprise a brake stack and an electromechanical actuator mechanically coupled to the brake stack. A first hydraulic chamber may also be mechanically coupled to the brake stack and in fluid communication with a first piston of the electromechanical actuator. A second piston may be in fluid communication with the first hydraulic chamber. The second piston may also be configured to translate towards the brake stack in response to a translation of the first piston.

    摘要: Systems and methods of controlling a brake system are provided. The system may include the step of detecting, by a controller, a failure of a first load cell of a first electromechanical brake actuator (EBA). The method may further comprise estimating, by the controller, a force of the first EBA using a force output from a second load cell, and commanding, by the controller, the first EBA in response to the estimated force of the first EBA.

    摘要: A braking system for an aircraft is disclosed herein. The braking system may comprise: a brake assembly; a hydraulic braking subsystem having a hydraulic brake actuator configured to operate the brake assembly; an electric braking subsystem and a hydraulic braking subsystem. During a flight, one of the electric braking subsystem and the hydraulic braking subsystem may be selected as a primary braking system. The braking system may be configured to command braking of a brake assembly by the hydraulic braking subsystem and the electric braking subsystem during an RTO phase of the flight. The braking system may be configured to command braking of a brake assembly by a secondary braking system in response to a failure of a primary braking system during the RTO phase of the flight.
