How is the 787 fuselage construction?
Composite fuselage of the Boeing 787 Dreamliner: (a) the fuselage barrel is a continuous construction build on a rotating mandrel through automated tape laying [13]; (b) the resulting monocoque shell has internal longitudinal stiffeners already built in [12]; (c) the highly integrated internal structure of the fuselage …
Has there ever been a Boeing 787 crash?
Once the best passenger jet manufacturer by far, the crashes and miscues with its 737 MAX have come to haunt the 787 Dreamliner; without the crashes. So far. But now the FAA is looking more closely at what and how Boeing manufactures its airplanes.
What are the fuselage and the wings of the Dreamliner a Boeing 787 made of?
composite materials
According to the Boeing company website, as much as “50\% of the primary structure including the fuselage and wing on the 787 will be made of composite materials.”2 The wings of the Dreamliner are composed of up to 50\% composite material by weight (80\% composite material by volume) and 20\% aluminum.
Who makes fuselage for Boeing?
Specifically, this is a role fulfilled by Spirit AeroSystems, which produces the fuselages before sending them to Boeing to join the assembly line. However, Spirit is based in Wichita, Kansas, whereas Boeing’s 737 factory is in Renton, Washington.
How are fuselage sections joined?
First, a series of frames in the shape of the fuselage cross sections are held in position on a rigid fixture. These frames are then joined with lightweight longitudinal elements called stringers. These are in turn covered with a skin of sheet aluminum, attached by riveting or by bonding with special adhesives.
Is 777 a Dreamliner?
The Boeing 787 ‘Dreamliner’ has revolutionized long-haul commercial air travel. It has allowed cheaper long-haul carriers to exist, while also unlocking new, long routes….Comparing the specifications.

Who makes 787 fuselage?
The 787 is composed of six fuselage sections manufactured by four Tier 1 airframers. Section 41, which includes the cockpit, galley, front doors and the first few rows of seats, is manufactured by Spirit AeroSystems (Wichita, Kan., U.S.).
Where is the 787 fuselage built?
Charleston
The fuselage sections are collectively built by, Vought in Charleston, South Carolina, (USA), Alenia in Italy, Kawasaki Heavy Industries in Japan and Spirit AeroSystems, in Wichita, Kansas, (USA).
Is the Boeing 787 fuselage 100\% composite?
The 787 fuselage is not a 100\% composite construction. Are the same methods used to join the wings? Yes, if you watch the second linked video in full, you can see the composite wings being bolted to the fuselage structure. The entire wing support structure looks to be a conventional metal structure.
What are the challenges of building a Boeing 787?
There are new challenges with any type of new construction technique, here are a few articles that outline the challenges: Boeing has said that the 787 is as easy to repair as traditional aluminum skin aircraft. One case in point is the Ethiopian Airlines aircraft ET-AOP damaged by fire.
How easy is it to repair a 787?
Boeing has said that the 787 is as easy to repair as traditional aluminum skin aircraft. One case in point is the Ethiopian Airlines aircraft ET-AOP damaged by fire. The procedure to fix it is to cut out the carbon fiber material and put a “cure in place” patch over the hole.
Why does the Boeing 787 have such a high aspect ratio?
The use of composite materials in the wing structure allows the 787 wing to have a higher aspect ratio (the square of the wing span divided by the wing area) than previous aircraft.
