	Boeing 787 Dreamliner Medium to Long-Range Jetliner

DESCRIPTION: The 787 Dreamliner program began as a response to the enormous Airbus A380. While Airbus was developing its first "super jumbo jet," Boeing chose to focus its resources on the more lucrative midsize market by developing a replacement for the 767 and A300. Boeing first explored a revolutionary design dubbed the Sonic Cruiser hoping to attract customers with increased speed, but studies of a more conventional concept continued as well. While not as radical looking as the Sonic Cruiser, this conventional design's promise to significantly cut operating costs through the use of advanced fuel efficient technologies proved very attractive to the airline market. Boeing has stated the 787 will be 15% to 20% more efficient and burn 17% less fuel than the 767 due to the innovative use of new technology. Perhaps the most challenging of these advances is the extensive use of lightweight composite materials that make up much of the wing and fuselage structures. While composites have been widely used in aviation since the 1980s, the 787 is the first commercial airliner to use the materials for the majority of its construction. The reduced weight of its structure coupled with aerodynamic improvements to reduce drag are said to account for about a third of the Dreamliner's fuel savings. Another third comes from improvements in engine technology while the remainder is due to advanced systems like its electrical architecture that doesn't require bleed air from the engines. The program was officially launched in 2004 under the name 7E7, the "E" representing efficient, when All Nippon Airways of Japan placed an order for 50 of the airliners. The name was later changed to the more conventional 787 in 2005, and the type has since attracted orders faster than any other airliner in Boeing's history. Unfortunately, its revolutionary technologies have come at the cost of significant development and production problems. The largest delays have resulted from Boeing's decision to make greater use of subcontractors in assembling the 787. Rather than building the entire aircraft at its factory near Seattle, Boeing chose to have complete subsystems built around the world and transported to Washington for final assembly. Major suppliers are located in Italy, Japan, Australia, Canada, as well as sites across the United States. Many of these subcontractors have had difficulties performing more complex subassembly tasks within Boeing's aggressive schedule. Part shortages, labor strikes, and redesign efforts prompted by excess weight have also contributed to delays that have extended development by at least 18 months. Thanks to these problems, Boeing has been forced to pay compensation to many of its customers as well as offer steep discounts on replacement aircraft until the 787 is ready for service. First flight had been planned for mid-2007 but will now occur no earlier than late 2008. Boeing must also maintain a very brisk flight test program in hope of meeting the first delivery date, currently scheduled for about September 2009. The first version to enter service will be the 787-8 base model. Boeing has also launched the lengthened 787-9 with higher passenger capacity and greater range as well as the 787-3 high-density variant with reduced fuel capacity for shorter routes. Boeing is planning a further stretched model called the 787-10 as well as a freighter version. Counting the three 787 variants currently in development, more than 900 orders had been placed by October 2008. Last modified 05 November 2008
