More Dreamliner Tech Trickles Down The Line

Boeing announced Monday a new carbon-fiber brake option will be available on the Next-Generation Boeing 737. The brakes (photo at right of 777 composite brakes) will reduce airframe weight, and lower operating costs for the advanced version of Boeing's standard-bearer medium range airliner.

The no-charge option will save up to 700 pounds in airplane weight, according to Boeing, and increase the wear life up to twice the number of landings. The reduction in weight and increased durability will lower maintenance and operating costs overall.

"Carbon brakes offer the same stopping performance as steel brakes but with the added benefit of a significant weight savings, which ultimately increases fuel efficiency," said Mike Delaney, 737 chief project engineer.

"Next-Generation 737s are already lighter than competing Airbus models," Delaney added. "This structural efficiency is a fundamental reason why Next-Generation 737s fly farther, higher and with better fuel efficiency than the competition."

"This new feature demonstrates our continued commitment to offer technology that brings value to our customers and continues to make the 737 the most capable airplane in the world's single-aisle market," added Delaney.

The carbon brakes, which will be supplied by Goodrich and Messier-Bugatti, will be available for deliveries starting in early 2008 -- after a two-month flight test program. The option also will be available for retrofit on all Next-Generation 737s.
