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
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.
