The airplane uses 20 percent less fuel than today’s similarly sized airplanes. It will also travel at a similar speed as today’s fastest wide bodies, Mach 0.85.
Composite materials make up 50 percent of the primary structure of the 787 including the fuselage and wing.
the team has incorporated airplane health-monitoring systems that allow the airplane to self-monitor and report systems maintenance requirements to ground-based computer systems.
New engines from General Electric and Rolls-Royce are used on the 787. Advances in engine technology are the biggest contributor to overall fuel efficiency improvements. The new engines represent nearly a two-generation jump in technology for the middle of the market[/size][/font] [/left]
