Abstract
A frame (1) for fuselage shells of an aircraft, the fuselage comprising a skin (3) and stringers (4), the frame (1) including: a plurality of sections (5), the sections (5) being separated by intermediate gaps corresponding to the position of the stringers (4) in the fuselage, each section (5) having a multi-cell configuration constituted by several modular elements (6) of composite material arranged in longitudinal direction, and a continuous inner cap (7) on top of the sections (5) and the intermediate gaps.
Claims20
A frame configured for a fuselage of an aircraft, wherein the fuselage includes a skin and stringers;
- and the frame comprises:
- sections each of which includes a multi-cell configuration formed by modular elements of composite material arranged in longitudinal direction, wherein each of the modular elements have a length shorter than a width of the modular element;
- intermediate gaps corresponding to positions of the stringers in the fuselage and each separating at least two of the sections;
- and
- an inner cap on top of the sections and on top of the intermediate gaps.
A fuselage shell for an aircraft comprising:
- a skin forming extending continuously around a longitudinal axis of the fuselage shell,
- stringers attached to an inside surface of the skin and oriented longitudinally;
- frames attached to the inside surface of the skin and oriented transverse to the longitudinal axis, wherein each of the frames include:
- modular elements oriented longitudinally, arranged side-by-side between adjacent ones of the stringers, connected to the inside surface of the skin and including inward facing surfaces opposite to the skin, wherein each of the modular elements have a length shorter than a width of the modular element;
- and
- an inner cap oriented transverse to the longitudinal axis and covering the inward surfaces of the modular elements and the inward surfaces of the stringers.
