It will also travel at speeds similar to today’s fastest wide bodies, about Mach 0.85. Production will begin in 2005. First flight is expected in 2007 with certification, delivery and entry into service occurring in 2008.
New 787DreamLiner will become the first commercial jet to be made with most of its primary structure consisting of composite materials.Some of the composite materials that will be used include graphite and toughened epoxy resin, and TiGr, a titanium/graphite composite. The graphite/epoxy material will make up the bilk of the composite materials used in the 787, while the titanium/graphite composite will be used for the wings.Titanium is a strong metal known for its light weight and durability. Graphite is a stable form of carbon. Boeing 787 (Dream Liner) will be the most advanced and efficient commercial airplane in its class and will set new standards for environmental responsibility and passenger comfort.
The Engines, Boeing’s demands will intend to make B787 (Dream Liner) significantly quieter and cleaner , more fuel efficiency and cheaper to maintain. A new generation of aircraft requiring a new generation of engine. Boeing is requiring engines producing up to around 70,000 lb. of thrust. The engine manufacturers are talking about reducing the number of compressor stages, reducing bleed air or shift away from using bleed air to pressurized cabin air and shift away hydraulic systems toward nearly all electric aircraft. All of those under study and final results are still unknown.
B787 will has approximately of Carbon fiber laminated composite materials around 57% of the main structure and 24% aluminum alloy, 11% titanium, and 8% steel. The 787 will have two 250kW generators to provide power for pressurization, deicing and hydraulic pumps. The 787 will have wireless IFE system, the aircraft’s interior will be broken up into broadcast areas. The 787 will have 5000 psi hydraulics system.
