Abstract: A brake control system for an aircraft is disclosed having a plurality of brake actuators. Each brake actuator includes a braked state imparting an unknown braking torque, and a parked state imparting a known braking torque. The system includes a controller to control the states of the brake actuators. In response to a parking signal, when at least one of the brake actuators is in the braked or parked state, the controller performs a parking procedure comprising maintaining a first brake actuator in the braked or parked state whilst changing the state of a second brake actuator from the braked state to the parked state. Also disclosed is an aircraft including the brake control system, a method of controlling a brake system for an aircraft, and a non-transitory computer readable storage medium.

Abstract: An actuator is disclosed including an actuator body mounted for movement over a range of motion, the range of motion including a first part and a second part, the first part being the range of motion extending between an end position and the second part. The actuator includes a motor coupled to the actuator body to move the actuator body in the first direction and a controller configured to control the supply of current to drive the motor. The mechanical resistance to movement of the actuator body in the first direction is higher in the first part of the range of motion than in the second part of the range of motion. The controller is configured such that any additional current supplied to the motor when the actuator body is in the first part of the range of motion is limited thereby causing the speed of the actuator body to reduce as the actuator body approaches the end position.

Abstract: A brake control system 200 and method 300 for controlling a park brake of an aircraft including a controller 201 configured to cause an increase in a brake torque of the park brake based of an indication to the controller. The indication is generated in response to touchdown of the aircraft.

Abstract: An aircraft braking system for an aircraft, the aircraft including first and second brakes, and first and second energy distribution systems for delivering energy to the first and second brakes to operate the respective first and second brakes. The aircraft braking system is switchable between: a first configuration, in which the first energy distribution system is coupled to the first brake and is isolated from the second brake, and the second energy distribution system is coupled to the second brake and is isolated from the first brake; and a second configuration, in which the first energy distribution system is coupled to both the first and second brakes.
