How long does it take to build a 787?
Boeing 787 Series: 25-40 days. Airbus A350 Series: ~2.5-3 months. Boeing 777: 50-60 days (~17 for assembly!) Boeing 747-8i: 3-4 months.
Where does Boeing assemble the 787?
North Charleston, South Carolina
The plan to consolidate production at Boeing’s 787 North Charleston, South Carolina, assembly plant this month is on schedule, the company said. Once finalized, the production rate of the 787 will be reduced from the current six planes a month to a rate of five planes per month.
How is the 787 fuselage construction?
The 787 fuselage design stipulates two basic composites fabrication operations: Stringer cutting and forming and fuselage skin fiber placement. The trick is in combining the stringers with the fiber-placed skin to enable a co-cured structure.
How many parts does a Boeing 787 have?
2.3 million parts
The 787 Dreamliner has about 2.3 million parts per airplane. They include everything from “fasten seatbelt” signs to jet engines and vary in size from small fasteners to large fuselage sections.
What material is the Boeing 787 made of?
composite
The Boeing 787 aircraft is 80% composite by volume. By weight, the material contents is 50% composite, 20% aluminum, 15% titanium, 10% steel, and 5% other [11]. Aluminum is used for the wing and tail leading edges; titanium is used mainly on engines and fasteners, with steel used in various areas.
How are aircraft fuselage sections joined together?
There is little to no welding used in aircraft construction. The large parts are assembled as sub-assemblies and then mounted into large jigs. The jigs are positioned together, and the pieces are spliced together with doublers or lap joints.
How are aircraft 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.
