Todd Johnson has worked on the development, commercialization, and sales sides of the composites industry since 2004. Popular single-aisle aircraft such as the A320 have used a range of parts made from composites, such as the fin and tailplane. If it will not contain the debris then the engine cannot be certified for flight. from Wichita, KS to North Charleston, NC, Horizontal Stabilizer With its lifecycle approach to design, Boeing created a flexible interior for the 787 family that can easily adapt as airline needs change. 85% annual winds With a maximum payload range of 350 miles, that's about 3 pounds per passenger mile. 12 LD-3s 54.4 m3 (1,960 ft3) The 787-8 Dreamliner can fly 242 passengers up to 7,355 nautical miles (13,620 km) in a typical two-class configuration, with 20 percent less fuel and emissions than the airplanes it replaces. 7 Is the Boeing Dreamliner made out of composites? Undertaking the design process without preconceived ideas enabled Boeing engineers to specify the optimum material for specific applications throughout the airframe. Every structural element of the 787 has undergone this type of life-cycle analysis and material types are based on a thorough and disciplined selection process. They allow a lighter, simpler structure, which increases airplane efficiency, reduces fuel consumption and reduces weight-based maintenance and fees. I dont think theres any reason to believe therell be more holes per se in a composite fuselage. The 787 will replace two Boeing aircraftthe single-aisle 757, which seats 200-280 pas-sengers and is no longer in pro-duction; and the twin-aisle 767, . 5 Pallets 58.8 m3 (2,075 ft3) New technology in the 787 nacelle is designed to maintain laminar flow over a longer portion of the surface than ever before, saving more fuel and emissions. The use of composites in the 787 is expected to provide a 3% fuel savings over the 767. In addition, the 787 offers many new passenger-pleasing features that provide unprecedented comfort, convenience and a great flying experience. The 2005 Boeing document that laid out the deadly Dreamliner crash scenario was an early mathematical analysis, prepared by structural-dynamics experts in the companys Phantom Works research unit. In the composite-plastic 787, by contrast, the lower fuselage is shattered, with multiple holes. Instead of a mechanical system of cables and pulleys that move the control surfaces on the wing and tail, fly-by-wire systems translate pilot inputs into electrical signals. Designers can shape products in a manner that is simply not possible with other materials and in the case of the 787, this makes for a more aerodynamic plane. from North Charleston, SC to Everett, WA, Horizontal Stabilizer The Boeing 787 Dreamliner is an all-new, super-efficient family of commercial airplanes that brings big-jet ranges and speed to the middle of the market. A report issued by the United Kingdom Civil Aviation Authority determined that the Boeing 787 is significantly quieter than the airplanes it replaces, on average between seven and eight decibels quieter on departure and up to three decibels quieter on arrival. For comparison, the 777 is only made up of 10% composites. . Regional Business Overall, this represented an 80 per cent reduction in the number of fasteners required when compared with a non composite barrel structure. This structure is as good as the 777, Jenks said. Airways and traffic allowances included While a typical bonded repair may require 24 or more hours of airplane downtime, Boeing has taken advantage of the properties of composites to develop a new line of maintenance repair capability that requires less than an hour to apply. See Google Maps. This approach offers weight savings on average of 20 per cent compared to more conventional (and outdated) aluminum designs. This high aspect ratio wing design combined with efficiency enhancing raked wing tips allow the 787 to be one of the fastest commercial aircraft (Mach 0.85 cruise speed) while consuming less fuel than today's comparably sized aircraft. By weight, the material contents is 50% composite, 20% aluminum, 15% titanium, 10% steel, and 5% other [11]. At least two different types of carbon fiber composites are used in the 787, carbon laminate and carbon sandwich. 16 LD-3s 72.5 m3 (2,560 ft3) "Boeing's 787 Dreamliner." Design choices never optimize one area at the expense of overall performance, economics, maintenance costs, or airplane availability. Higher speed: At Mach 0.85, the 787 is as fast as the 777 and 747 and faster than other airplanes of its size. This rapid composite repair technique offers temporary repair capability to get an airplane flying again quickly, despite minor damage that might ground an aluminum airplane. That report was the result of a painstakingly detailed review of certification processes followed by the Federal Aviation Administration (FAA) and the European Aviation Safety Agency (EASA), a search of the technical literature, and interviews with repair and maintenance experts, FAA and EASA officials, and Boeing representatives. For instance, the report states (on page 4): "The material properties of composites make them more resistant to fatigue and corrosion than metal, which leads to lower maintenance costs." This is faster than other airplanes serving in this size range and allows an airline to have the same speed airplanes with the same range and economics in three distinct sizes. The 787 is an all-new design with no legacy constraints, and it achieves many firsts in commercial aviation. 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. In addition, it became the first passenger aircraft in which the fuselage and wings were made almost entirely of composite materials. Boeing has also implemented a rigorous process for evaluating the use of aluminum that combines likelihood of corrosion with consequence of corrosion. Low maintenance costs: The strong, durable composites that make up the 787 fuselage contribute to a 30 percent reduction in airframe maintenance costs than for previous-generation airplanes.
