Filed:

Jul 11, 2012

Appl. No.:

13/546936

Inventors:

Eric D. Cahill - Troy OH, US
Dale Prentice - Tipp City OH, US

Assignee:

GOODRICH CORPORATION - Charlotte NC

International Classification:

B64C 25/46

US Classification:

701 3

Abstract:

Systems and methods are disclosed for detection of dragging brakes for use in, for example, an aircraft. A method is provided comprising calculating, by a brake controller, a slip ratio based upon an aircraft speed and a speed of an aircraft wheel, determining, by the brake controller, that the slip ratio is above a threshold value, and sending, by the brake controller and in response to the slip ratio being above the threshold value, a dragging brake signal to an aircraft component.

Abstract:

A system, apparatus and method provide a means for testing operation of vehicle brake system. More particularly, a brake actuator is automatically commanded to engage a brake disk stack while the vehicle is in a benign state. An engagement force applied to the brake-disk stack by the actuator then is determined, and the engagement force is compared to a first threshold value. If the engagement force is within a predetermined range of the first threshold value, it is concluded that the brake system is operating normally, otherwise it is concluded that the brake system is operating abnormally.
