FIELD: aeronautical engineering.
SUBSTANCE: invention relates to aeronautical engineering. The fuselage skin is jointed to stringer set and elliptical profile bulkheads that form, together with the upper and lower beams-walls, a rectangular structure with the height-to-width ratio of at least 1:2 in cross section and 2:1 lengthwise. The bulkhead upper and lower belts are jointed together by posts-ties, their height being equal to the cockpit height.
EFFECT: higher rigidity and strength.
