The Boeing 787 is a dream jet. He received a similar nickname in aviation. The power structure, wings and fuselage are 50% composite. The dreamliner’s fuel efficiency gains are driven by new General Electric and Rolls-Royce engines. The flight range of this model is 18,418 km. The aircraft is able to cover the distance without landing, which is 17.5 hours in time. Flight comfort is ensured by well-balanced pressure, fresh air and an impressive spacious cabin. Optimum pressure (1830 m above sea level) is created using a pressurization system. Composite materials have made it possible to enlarge the windows, which makes the interior bright.
