Abstract:
Systems and methods for an aircraft emergency and park brake system are disclosed. The emergency and park brake system may comprise an emergency and park brake controller. The emergency and park brake controller may be configured to receive brake signals from mechanical and electrical inputs, generate a braking command comprising data from the brake signal, and transmit the braking command to control braking force. The emergency and park brake controller may receive brake signals from multiple locations including from the aircraft and from a remote location.
Abstract:
A brake control system (BCS) may comprise a first controller, a second controller in electronic communication with the first controller, and a valve comprising a first coil and a second coil. The first controller may be configured to actuate the valve via the first coil. The second controller may be configured to actuate the valve via the second coil. The first controller may be configured to disable the second controller to take over control of the valve.
Abstract:
A valve includes an electrical park valve configured to receive an electrical park signal and to allow hydraulic fluid to flow through a first electrically-controlled channel in response to the signal indicating a parking request, and a main valve configured to receive the hydraulic fluid from the first electrically-controlled channel and to allow the hydraulic fluid to flow to a braking actuator in response to receiving the hydraulic fluid. The valve also includes an electrical emergency control valve configured to allow the hydraulic fluid to flow through a first control channel in response to a request for emergency braking. The valve also includes an emergency enable valve configured to receive the hydraulic fluid from the first control channel and to allow the hydraulic fluid to flow to the braking actuator in response to receiving the hydraulic fluid from the electrical emergency control valve.
Abstract:
A displacement sensor includes a resistive element and a wiper element. The wiper element is separated from the resistive element in a parked mode the wiper element is in sliding electrical contact with the resistive element in a sensing mode. A user input interface may be coupled to at least one of the resistive element and the wiper element, wherein whether the displacement sensor is in the parked mode or the sensing mode is dependent on actuation of the user input interface.

Abstract:
A brake system is provided. The brake system may comprise a controller, a vehicle management system (VMS), a shut-off valve (SOV), an outboard valve (OBV), an inboard valve (IBV), a control module, an emergency/park power source, and a tangible, non-transitory memory configured to communicate with the controller. The VMS may be in communication with the controller. The control module may be in communication with the SOV, OBV, and IBV. The SOV may be in communication with the controller. The OBV may be in communication with the controller and in fluid communication with the SOV. The IBV may be in communication with the controller and in fluid communication with the SOV. The emergency/park power source may be in fluid communication with the SOV.
Abstract:
Systems and methods for reducing the speed of an aircraft are disclosed herein. An electronic brake control system may include a first braked wheel of a landing gear system, a brake pedal electronically coupled to the first braked wheel, and a first actuator. The first actuator may be configured to deliver a scalable clamping force on the first braked wheel via a brake stack. The first actuator may be configured to deliver an emergency maximum clamping force on the first braked wheel in response to the electronic brake control unit being in an emergency condition braking mode and a signal being received proportional to the brake pedal displacement. The emergency maximum clamping force results in the first actuator being driven in an overdriven state.
Abstract:
A method is disclosed that comprises severing an I/O channel between an EMAC and an aircraft component; sending a test signal to the brake system controller; receiving, from the brake system controller, a feedback signal to the test signal; and determining an appropriateness of the feedback signal.
