BACKGROUND-
During the late 1990s, Boeing began considering replacement aircraft programs as sales for the 767 and Boeing 747-400 slowed. The company proposed two new aircraft, the 747X, which would have lengthened the 747-400 and improved efficiency, and the Sonic Cruiser, which would have achieved 15% higher speeds (approximately Mach 0.98) while burning fuel at the same rate as the existing 767.Market interest for the 747X was tepid, but the Sonic Cruiser had brighter prospects. Several major airlines in the United States, including Continental Airlines, initially showed enthusiasm for the Sonic Cruiser concept, although they also expressed concerns about the operating cost.
The global airline market was disrupted by the September 11, 2001 attacks and increased petroleum prices, making airlines more interested in efficiency than speed. The worst-affected airlines, those in the United States, had been considered the most likely customers of the Sonic Cruiser, and thus Boeing officially cancelled the Sonic Cruiser on December 20, 2002. Changing course, the company announced an alternative product using Sonic Cruiser technology in a more conventional configuration, the 7E7, on January 29, 2003.The emphasis on a smaller midsize twinjet rather than a large 747-size aircraft represented a shift from hub-and-spoke theory towards the point-to-point theory,in response to analysis of focus groups.
On April 26, 2004, Japanese airline All Nippon Airways became the launch customer for the Dreamliner, by announcing a firm order for 50 aircraft with deliveries to begin in late 2008.All Nippon Airways' order was initially specified as 30 787-3, 290–330 seat, one-class domestic aircraft, and 20 787-8, long-haul, 210–250 seat, two-class aircraft for regional international routes such as Tokyo Narita–Beijing. The aircraft would allow All Nippon Airways to open new routes to cities not previously served, such as Denver, Moscow, and New Delhi.The 787-3 and 787-8 were to be the initial variants, with the 787-9 entering service in 2010.
DESIGN-
The 787 was designed to be the first production airliner with the fuselage assembled with one-piece composite barrel sections instead of the multiple aluminum sheets and some 50,000 fasteners used on existing aircraft.Boeing selected two new engine types to power the 787, the General Electric GEnx and Rolls-Royce Trent 1000.Boeing stated the 787 would be approximately 20 percent more fuel-efficient than the 767 with approximately 40 percent of the efficiency gain from the engines,plus gains from aerodynamic improvements,increased use of lighter-weight composite materials, and advanced systems.The 787-8 and -9 were intended to be certified to 330 minute ETOPS capability.
During the design phase, the 787 underwent extensive wind tunnel testing at Boeing's Transonic Wind Tunnel, QinetiQ's five-meter wind tunnel at Farnborough, UK, and NASA Ames Research Center's wind tunnel, as well as at the French aerodynamics research agency, ONERA. The final styling of the aircraft was more conservative than earlier proposals, with the fin, nose, and cockpit windows changed to a more conventional form.

PRE-FLIGHT GROUND TESTING-
As Boeing worked with its suppliers on early 787 production, the aircraft design had proceeded through a series of test goals. On August 7, 2007, on-time certification of the Rolls-Royce Trent 1000 engine by European and US regulators was received.On August 23, 2007, a crash test involving a vertical drop of a partial composite fuselage section from about 15 ft (4.6 m) onto a 1 in (25 mm)-thick steel plate occurred in Mesa, Arizona;the results matched what Boeing's engineers had predicted, allowing modeling of various crash scenarios using computational analysis instead of further physical tests.While critics had expressed concerns that a composite fuselage could shatter and burn with toxic fumes during crash landings, Boeing's test data indicated no greater toxicity versus conventional metal airframes.The crash test was the third in a series of demonstrations conducted to match FAA requirements, which included additional certification criteria owing to the 787's introduction of wide-scale composite materials.
The alternative GE GEnx-1B engine achieved certification on March 31, 2008.On June 20, 2008, the 787 team achieved "Power On" of the first aircraft, powering and testing the aircraft's electrical supply and distribution systems.A non-flight 787 test airframe was built for static testing, and on September 27, 2008, over a period of nearly two hours, the fuselage was successfully tested at 14.9 psi (102.7 kPa) differential, which is 150 percent of the maximum pressure expected in commercial service (i.e., when flying at maximum cruising altitude).In December 2008, the Federal Aviation Administration (FAA) passed the maintenance program for the 787.
FLIGHT TEST PROGRAM-
On December 15, 2009, Boeing conducted the Dreamliner's maiden flight with the first 787-8, originating from Snohomish County Airport in Everett, Washington, at 10:27 am PST,and landing at Boeing Field in King County, Washington, at 1:35 pm PST.Originally scheduled for four hours, the test flight was shortened to three hours because of bad weather. Boeing's schedule called for a 9-month flight test campaign (later revised to 8.5 months).The company's previous major aircraft, the 777, took 11 months with nine aircraft, partly to demonstrate 180-min ETOPS, one of its main features.
VARIANTS-
Boeing has offered three variants of the 787 from the program launch in 2004. The 787-8 is the first variant produced and is to be followed by the 787-9.
787-8:-
The 787-8 is the base model of the 787 family, with a length of 186 feet (57 m) and a wingspan of 197 feet (60 m) and a range of 7,650 to 8,200 nautical miles (14,170 to 15,200 km), depending on seating configuration. It is the only 787 variant, and the third Boeing widebody (after the 747SP and the 777-200LR) with a wingspan wider than the length of the fuselage. The 787-8 seats 210 passengers in a three-class configuration.The variant was the first of the 787 line to enter service, entering service in 2011. Boeing is targeting the 787-8 to replace the 767-200ER and 767-300ER, as well as expand into new non-stop markets where larger planes would not be economically viable. Two-thirds of 787 orders are for the 787-8.

787-9:-
The 787-9 will be the first variant of the 787 with a "stretched" or lengthened fuselage, seating 250–290 in three classes with a range of 8,000 to 8,500 nautical miles (14,800 to 15,750 km).This variant differs from the 787-8 in several ways, including structural strengthening, a lengthened fuselage, a higher fuel capacity, a higher maximum take-off weight (MTOW), but with the same wingspan as the 787-8.The targeted entry into service (EIS) date, was originally planned for 2010,but by October 2011 deliveries were scheduled to begin in early 2014.Boeing is targeting the 787-9 to compete with both passenger variants of the Airbus A330 and to replace their own 767-400ER. Like the 787-8, it will also open up new non-stop routes. The firm configuration was finalized on July 1, 2010.
