Goodrich Corp. (Charlotte, N.C., USA) on March 3 announced that its electric brake system for the Boeing 787 Dreamliner has completed all required dedicated flight test conditions. The achievement follows a comprehensive development and qualification program involving multiple Goodrich business units and collaboration with Boeing.
The braking system incorporates the latest iteration of Goodrich's proprietary DURACARB carbon/carbon composite heat sink material, which the company says provides good brake performance and up to 35 percent better brake life than competing carbon friction materials. Required test conditions included extensive on-aircraft testing of the wheels and electric brake hardware, as well as validation of the proprietary software incorporated in the electric brake actuator controllers. Maximum brake energy testing was completed at Edwards Air Force Base, Calif., USA.
Brian Brandewie, president of Goodrich's Aircraft Wheels and Brakes business said, "We anticipated demand for an alternative to traditional, hydraulically actuated braking, and began the pursuit of electrically actuated braking technology more than 15 years ago. The 787 system represents our sixth generation of electric brakes. Goodrich is again honored to be part of aviation history by being a supplier for the world's first electric brake system on a commercial airplane. We look forward to working with Boeing and the launch customer airlines to ensure a successful entry into service."
To date, the majority of announced 787 customers have selected the Goodrich electric brake system, including All Nippon Airlines, the airplane's launch customer.
