波音787-800 DREAMLINER 2 3D模型

The Boeing 787 Dreamliner is a long-range, mid-size wide-body, twin-engine jet airliner developed by Boeing Commercial Airplanes. Its variants seat 210 to 335 passengers. It is Boeing's most fuel-efficient airliner and the world's first major airliner to use composite materials as the primary material in the construction of its airframe. The 787 has been designed to be 20% more fuel efficient than the 767 it is to replace. The 787 Dreamliner's distinguishing features include mostly electrical flight systems, a four-panel windshield, noise-reducing chevrons on its engine nacelles, and a smoother nose contour. It shares a common type rating with the larger Boeing 777, allowing qualified pilots to operate both models, due to related design features.
