Abstract
An emergency park brake system of an aircraft may include an electrical power interface, an electromechanical actuator, and a hydraulic brake valve. The electrical power interface may be configured to receive electrical power from a power source. The electromechanical actuator may be in selective power receiving communication with the electrical power interface and the electromechanical actuator may be mechanically coupled to and configured to selectively actuate the hydraulic brake valve. The electrical connection between the electromechanical actuator and the electrical power interface may be based on an emergency braking input.
Claims7
An emergency park brake system of an aircraft, the emergency park brake system comprising:
- an emergency park brake controller configured to receive emergency braking input and configured to generate both an emergency braking command and a power supply condition in response to the emergency braking input;
- an electrical power interface configured to receive electrical power from a power source;
- an electromechanical actuator;
- a hydraulic brake valve, wherein the electromechanical actuator is mechanically coupled to and configured to selectively actuate the hydraulic brake valve;
- a first electrical communication pathway extending between the emergency park brake controller and the electrical power interface;
- a second electrical communication pathway extending between the emergency park brake controller and the electromechanical actuator;
- and
- a selective electrical connection extending between the electrical power interface and the electromechanical actuator, wherein the selective electrical connection is configured to be disconnected in response to the power supply condition not being satisfied;
- wherein the first electrical communication pathway, the electrical power interface, and the selective electrical connection form a pathway that is separate from the second electrical communication pathway extending between the emergency park brake controller and the electromechanical actuator.
