Boeing hinted about its proposed next generation jet liner B797 at Paris Air show.
Boeing revealed that fuselage and wings of new 797 will be made of carbon-fiber plastic composite, and will not have the typical airliner cross-section.
Mike Delaney, Boeing vice president in charge of new airplane development, said the plane — like the 787 Dreamliner — will have an all-composite airframe.
Boeing has never built a composite fuselage in the Puget Sound region. The various composite fuselage sections for the Dreamliner are made in North Charleston, South Carolina; Wichita, Kansas; and Nagoya, Japan.
Building the 797 fuselage will require further heavy investment, wherever Boeing decides to locate that work.
According to a Boeing spokesman who attended the Paris presentation, Delaney said Boeing is considering all options for fabricating the composites, including various new out-of-autoclave and resin infusion methods.
He said the decision on which manufacturing process is used will be based on multiple factors, including the quality of the parts and the time involved in the fabrication.
Delaney also described the proposed 797 fuselage as having a “hybrid cross-section,” meaning having characteristics of both a single-aisle and a widebody fuselage.
Boeing’s mantra that the jet will have “widebody comfort” with “single-aisle economics.”
