Goodrich Corp. (Charlotte, N.C., USA) reported on Feb. 13 that it has recently completed flight testing of its new carbon brake for the U.S. Air Force's fleet of C-130 transport aircraft, demonstrating a significant reduction in brake cooling time and enabling quicker aircraft turnaround.
According to Jeff Atkinson, director of military programs at Goodrich's Aircraft Wheels and Brakes business, "Successful U.S. Air Force flight testing demonstrated the current 65-minute mandatory steel brake cooling time after a heavy landing can be reduced to just five minutes when using our new carbon brakes. This now allows the aircraft and flight crew to quickly depart tactical areas after unloading cargo, without having to wait over an hour for the brakes to cool down."
Goodrich is currently delivering its new C-130 carbon brake and boltless wheel to the U.S. Air Force to support fleet retrofit activity beginning in early 2012. Goodrich's C-130 boltless wheel and DURACARB carbon brake provides eight times longer brake life and six times longer wheel life than the current wheel and brake system. The boltless aircraft wheels employ a lock-ring design, reducing maintenance time and cost, in addition to reduced parts count, when compared to traditional bolted aircraft wheels.
