Bair traces the origins of the 787 to the mid 1990s, "when we knew we had to put together a replacement for the Boeing 767. HEPA filters leave the air essentially particle free and are effective at removing bacteria, viruses, fungi, and a new gaseous filtration system, unique to the 787, removes common irritants that have a drying effect. So to convince the FAA that its computer model matches real-world results, Boeing performed some physical tests not required on previous metal planes. The highest survivable impact in a crash landing is considered to be about 20g, meaning a nearly instantaneous deceleration equal to 20 times the acceleration caused by gravity. In addition to using a robust structural design in damage-prone areas, the 787 has been designed with the capability to be repaired in exactly the same manner that airlines would repair an airplane today with bolted repairs. 1 Which composite material is mostly used in Boeing 787? The Boeing 787 Dreamliner has revolutionised the aviation industry through the application of sonic-boom busting technology: ie, composites. Composites as the name suggests is a combination of materials with different properties arranged in layer-by-layer manner so that we get the desirable properties. Boeing explains that, "in operation, the (composite) structure is more durable and does not corrode or fatigue like metals". of smaller aircraft supplanting New technologies are integrated while still maintaining a significant amount of commonality with other Boeing airplanes, particularly the 777. GoldCare is a tailored set of services designed to provide flexible solutions for material management, engineering, and maintenance execution while reducing costs and streamlining processes. The major structural elements of Boeing's 787 Dreamliner are made of more carbon 'sandwich' composites and . Familiar Boeing controls, displays and procedures all support shorter transition periods to the 787 from other Boeing family members, enabling efficient Mixed Fleet Flying. But unlike homogeneous metals, multilayered composites are very difficult to simulate accurately on a computer, Feraboli said. Titanium use has been expanded on the 787 to roughly 14 percent of the total airframe. Overall, there is a place for several different materials in the aircraft production cycle.
