Aircraft, fuselages, and associated methods

A fuselage, comprising:

• a skin defining an outer shape of the fuselage and including:
• an outer face-sheet defining an outer side of the skin;
• an inner face-sheet defining an inner side of the skin;
• and
• a plurality of core sections positioned between the outer face-sheet and the inner face-sheet;
• a structural frame operatively coupled to the inner side of the skin, and
• stringers that extend longitudinally along the inner side of the skin, wherein the stringers consist of six stringers with two stringers on each lateral side of the fuselage defining a window region on each lateral side of the fuselage and with one stringer on each lateral side of the fuselage collectively defining a floor interface of the fuselage.

A method of constructing a fuselage, comprising:

• forming a skin, including:
• forming an outer face-sheet to define an outer shape of the fuselage and an outer side of the skin;
• positioning a plurality of core sections on an inner side of the outer face-sheet;
• and
• forming an inner face-sheet over the plurality of core sections to define an inner side of the skin;
• and
• operatively coupling a plurality of frame members to the inner side of the skin at spaced apart intervals longitudinally along the fuselage;
• wherein the positioning the plurality of core sections includes positioning the plurality of core sections longitudinally spaced-apart along the inner side of the outer face-sheet, and wherein the forming the inner face-sheet includes forming the inner face-sheet over the plurality of core sections to define a plurality of cavities, within which the plurality of core sections are positioned;
• and
• wherein following the forming and the operatively coupling, each cavity of the plurality of cavities is positioned between adjacent frame members of the plurality of frame members, and the plurality of core sections and the plurality of cavities are elongate in a circumferential direction around the fuselage.

A fuselage, comprising:

• an outer face-sheet defining an outer side of the skin;
• an inner face-sheet defining an inner side of the skin;
• and
• a plurality of core sections positioned between the outer face-sheet and the inner face-sheet;
• a structural frame operatively coupled to the inner side of the skin, wherein the structural frame includes a plurality of frame members operatively coupled to and extending circumferentially around the inner side of the skin, wherein the frame members are spaced longitudinally along the fuselage;
• and
• stringers that extend longitudinally along the inner side of the skin, wherein within a section of the fuselage the stringers consist of six stringers with two stringers on each lateral side of the fuselage defining a window region on each lateral side of the fuselage and with one stringer on each lateral side of the fuselage collectively defining a floor interface of the fuselage;
• wherein the outer face-sheet and the inner face-sheet collectively define a plurality of cavities spaced longitudinally along the fuselage, wherein a core section of the plurality of core sections is positioned within each cavity of the plurality of cavities.
