The Boeing Co. (Seattle, Wash.) announced on Aug. 4 that it has earned certification from the U.S. Federal Aviation Administration for its new carbon/carbon brakes designed for the Next-Generation 737.
The brakes, supplied by Messier-Bugatti (Vélizy-Villacoublay, France), also entered service last week when Boeing delivered a Next-Generation 737-700 to Delta Air Lines, the first of 10 737-700s the airline will receive over the next several years.
The carbon fiber brakes weigh 700 lb/320 kg less than high-capacity steel brakes for Next-Generation 737-700, -800 and -900ER (Extended Range) airplanes; and 550 lb/250 kg less than standard-capacity steel brakes for Next-Generation 737-600s and -700s. Reduced weight contributes to reductions in associated fuel burn and CO2 emissions depending on airline operations.
Delta Air Lines is coupling lighter-weight carbon fiber brakes with drag- and emissions-reducing blended Wwnglets to improve operating and fuel efficiency simultaneously on its Next-Generation 737s. Delta's stated goal is to have greater flexibility to serve more markets with existing aircraft, further enhancing the largest international expansion in Delta's history.
