The Boeing 787 Dreamliner is a twin-engine passenger jet with a typical cruising speed of 587 miles per hour that can seat up to 330 passengers depending on configuration. The 787 has a range between 2,500 and 8,500 nautical miles.Continue Reading
The Boeing 787 Dreamliner is an advanced passenger plane that achieves high sustained speeds with up to 20 percent better fuel efficiency than older planes. This additional efficiency is due in large part to the use of lightweight composite materials in the 787's design that yield substantial weight savings compared to traditional materials. Nearly 50 percent of the 787's weight is accounted for by composite materials, while only 20 percent of its structure is composed of aluminum. In contrast, older planes are often composed of 50 percent or more aluminum by weight.
The 787 incorporates a raked wing and winglet design with a wingspan of 197 feet that is optimized for efficiency on longer flights. One General Electric GEnx-1b or Rolls-Royce Trent 1000 turbofan engine producing between 68,000 and 76,000 foot-pounds of thrust is located under each wing of the aircraft. The Dreamliner's maximum operational weight is 553,000 pounds, and its maximum fuel capacity is 36,641 gallons. The 787's maximum operational altitude is 43,000 feet, and it can achieve a maximum speed of 595 mph at an altitude of 35,000 feet.Learn more about Airplanes & Helicopters
