  • Patent number: 9079366
    Abstract: The invention relates to a production method for producing seamless, integral aircraft fuselage sections. The method comprises the following steps: a) application of a first vacuum film to a stable winding core and evacuation of the first vacuum film, b) depositing of the fuselage section in layers on the winding core by wrapping the same, c) application of an outer mold that is unstable compared to the stable winding core, to the fuselage section, wherein the winding core stabilizes the outer mold, d) application of a second vacuum film to the outer mold, e) aeration of the first vacuum film and evacuation of the second vacuum film in order to draw the fuselage section closer to the outer mold and detach it from the winding core at least in one region, a) curing of the entire arrangement in an autoclave to produce the finished fuselage section.
