FIELD: aeronautics; aviation; cosmonautics.
SUBSTANCE: claimed invention relates to aircraft elements, in particular, manufactured using cellular panels. Folded core panel comprises top and bottom face sheets and a first folded core. Said core is attached to the face sheets and has a corrugated zigzag pattern. Said pattern has a plurality of peaks, valleys and non-vertical faces extending between the plurality of peaks and valleys. Plurality of first peaks comprises a combination of surface profiles. Profiles are selected from angular, round and flat surface profiles, selectively located in the first folded core.
