During cruise, the wing trailing edge automatically adjusts upward and downward to continually optimize the camber for maximum efficiency. Invoicing / correspondence: Factory No. The 787's fly-by-wire control system is so advanced that it optimizes the shape (or "camber") of the wing automatically to save the most fuel. In turn, those composites get used in the fuselage, wings, tail, doors, and interior. The barrel fuselage was manufactured in single pieces which removed the need for 1,500 aluminium sheets and 50,000 screws! For example, the US-based carrier shares that titanium use has increased on the 787 to approximately 14% of the total airframe due to the initiative. Aluminum is used for the wing and tail leading edges; titanium is used mainly on engines and fasteners, with steel used in various areas. 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. This type of analysis has resulted in an increased use of titanium as well. It doesnt shatter and disperse in lots of pieces, Mooney said. (PDF) Brief Comparison of Composites used in Boeing 777 and 787 The Boeing 787 Dreamliner is an American wide-body jet airliner manufactured by Boeing Commercial Airplanes. Big sails on light boats place enormous stress / loads on the boats and composites provide the solution. The windows also dim at the touch of a button, allowing passengers to look outside when they wish and still maintain a dimmed cabin when appropriate. As a stretch of the 787-8, the 787-9 can fly more passengers and cargo farther -- 290 passengers over 7,635 nautical miles (14,140 km) - yet with the same 20 percent better fuel and emissions, allowing airlines to grow routes first opened by the 787-8.
