Abstract
An emergency autoland braking system for aircraft includes an electromechanical actuator configured to provide a braking force to rudder pedals for actuating a braking system without altering the existing braking system of the aircraft. An equalized braking force may be applied to both rudder pedals via a force balancing mechanism and a single linear actuator, or differential braking force may be applied via independent linear actuators. The system is compatible with both open and closed loop control for commanding a braking force.
Claims11
An emergency autoland braking system for aircraft, comprising:
- a cable having a first end and a second end;
- a first cam operatively coupled to the first end of the cable, wherein the first cam is configured to rotate via pulling of the cable thereby actuating a left brake arm;
- a second cam operatively coupled to the second end of the cable, wherein the second cam is configured to rotate via pulling of the cable thereby actuating a right brake arm;
- a pulley, wherein the cable is routed through the pulley;
- and
- a linear actuator operatively coupled to the pulley for adjusting a position of the pulley, wherein actuation of the linear actuator applies equal tension to the first and second ends of the cable via the pulley thereby adding an equal braking force to the left brake arm and the right brake arm.
