what is a BOEING 787?
The Boeing 787 Dreamliner is an American wide-body airliner developed and manufactured by Boeing Commercial Airplanes. After dropping its unconventional Sonic Cruiser project, Boeing announced the conventional 7E7 on January 29, 2003, which focused largely on efficiency. The program was launched on April 26, 2004, with an order for 50 aircraft from All Nippon Airways (ANA), targeting a 2008 introduction. On July 8, 2007, a prototype 787 without major operating systems was rolled out; subsequently the aircraft experienced multiple delays, until its maiden flight on December 15, 2009. Type certification was received in August 2011, and the first 787-8 was delivered in September 2011 and entered commercial service in October 2011, with ANA.
787's describtions:
The initial 186-foot-long (57 m) 787-8 typically seats 248 passengers over a range of 7,305 nmi (13,529 km; 8,406 mi), with a 502,500 lb (227.9 t) MTOW compared to 560,000 lb (250 t) for later variants.The stretched 787-9, 206 ft (63 m) long, can fly 7,565 nmi (14,010 km; 8,706 mi) with 296 passengers.
At launch, Boeing targeted the 787 with 20% less fuel burn compared to aircraft like the Boeing 767. It could carry 200 to 300 passengers on point-to-point routes up to 8,500 nautical miles [nmi] (15,700 km; 9,800 mi), a shift from hub-and-spoke travel. The twinjet is powered by General Electric GEnx or Rolls-Royce Trent 1000 high-bypass turbofans. It is the first airliner with an airframe primarily made of composite materials and makes greater use of electrical systems. Externally, it is recognizable by its four-window cockpit, raked wingtips, and noise-reducing chevrons on its engine nacelles. Development and production rely on subcontractors around the world more than for previous Boeing aircraft. Since March 2021 final assembly has been at the Boeing South Carolina factory; it was formerly in the Boeing Everett Factory in Washington state.
