Abstract : Fourteen dynamometer tests were performed on a B.F. Goodrich 2-727 brake assembly to investigate the characteristics inherent in modern brake design which are considered as indicators for brake induced landing gear strut chatter. The tests were designed to simulate normal service conditions experienced by the brake as part of the USAF T-38A aircraft system. Data from nine simulated landing roll tests and five simulated taxi tests were used to determine the slopes of the instantaneous coefficient of kinetic friction versus relative rubbing velocity curves for 10 ft/sec squared, 8 ft/sec squared, and 6 ft/sec squared deceleration conditions.
