The 787 meets the FAA's requirement that passengers have at least as good a chance of surviving a crash landing as they would with current metal . This structure is as good as the 777, Jenks said. Airways and traffic allowances included Operators appreciate the two widebodies fantastic balance of economics and customer experience on long-haul services. Composite materials have many advantages.
They were investigated, said Boeing spokeswoman Lori Gunter. Benefits include reduced weight, less complexity (reduced maintenance) - while maintaining that all important structural strength. The more-electric architecture of the 787 Dreamliner family eliminates the pneumatic and bleed-air system. With its lifecycle approach to design, Boeing created a flexible interior for the 787 family that can easily adapt as airline needs change. The rudder has large dimension, complicated shape structure, and extensive use of carbon fiber composite materials. This is a key reason why over half of both the A350 and 787 builds are made of composite materials. In fact, the noise footprint of the 787 is more than 60 percent smaller than the airplane it replaces. All airliners entering service since 1990 comply with that ban. Bair traces the origins of the 787 to the mid 1990s, "when we knew we had to put together a replacement for the Boeing 767. Only Boeing offers a modern, optimized and winning airplane in every market. Why not ask us? The 787's cabin is pressurized to a new maximum level of 6,000 feet; 2,000 feet lower than most other aircraft. cycle. Additionally, the weight savings help carriers transport more passengers while burning less fuel and flying greater distances.
Composite material used in Boeing 787 raises safety questions The major structural elements of Boeing's 787 Dreamliner are made of more carbon 'sandwich' composites and .

The blade technology has advanced tremendously since the days of the Rolls-Royce RB211. Composites in the airframe have maintenance advantages too. 787 More-Electric Architecture Certification is expected this fall. Because there are things that are new about this, weve gone way, way beyond what might have been basic requirements, Jenks said. The sweptback wings on the 787 were only possible because of the "increased malleability of composites" compared with metal.
Recent Developments & New Business Revenue Opportunities in Aerospace Without preconceived ideas, Boeing engineers were able to specify the optimum material for specific applications throughout the airframe. No other commercial airplane in Boeing's history have ever used so many composites in its airframe and primary structure. 242 two-class passengers, 254,000-kg (560,000-lb) MTOW Unique carbon-fiber makeup of Boeing's 787 raises safety concerns By Dominic Gates, McClatchy/Tribune news July 3, 2010 Advertisement When a Boeing 777 lost power and crashed short of the runway at London Heathrow Airport in 2008, the landing gear collapsed, and a strut pierced the passenger floor. In an unpublished paper, Yates dismissed the FAA fire tests because they were done on an intact fuselage, which is not typical in a real crash. In addition to lowering the overall airplane weight, moving to a composite primary structure promises to reduce both the scheduled and nonroutine maintenance burden on the airlines. Composites use on the 787 should have been more varied and applied more selectively to meet discrete mechanical loading requirements The crux of the problem with composites vis-a-vis the 787, said Byrne, is that the composites industry's immaturity makes capital outlay unusually expensive. operating economics and higher The 787 is also quieter for airport communities than any The chief breakthrough material technology on the 787 is the increased use of composites.
