Boeing 787 Dreamliner is a medium-sized twin-engine (power) wide-body medium and long-range transport aircraft being developed and produced by Boeing Civil Aircraft Group. It is the first brand-new model launched by Boeing in 1990 after the launch of Boeing 777 in 14. Boeing 787 series belongs to 200-300-seat aircraft, and its range can cover 6500- 16000 km depending on the specific aircraft type. Boeing emphasizes that the 787 is characterized by its extensive use of composite materials, low fuel consumption, fast cruising speed, high efficiency and comfortable cabin environment, and can realize more point-to-point non-stop direct flights.

Extended data:

Boeing 787 adopts the technology and airframe design of sonic cruiser, and 7E7' s main structure (including wing and fuselage) adopts advanced composite materials. Boeing 787 has a number of technological innovations, the most striking of which is that about half of the fuselage of Boeing 787 is made of lighter and stronger composite materials instead of aluminum alloy. It is the first civil jet with composite material as the main material.
