FIELD: transport.
SUBSTANCE: insulation set (19-22) for airframe is fastened on lengthwise side (41, 41a, 41b) of ribs (32, 32a, 32b, 32c) and arranged to be completely closed by foil (11) and to stay inside airframe covered by inner and outer coatings. Proposed design uses fireproof insulation and fireproof barrier layer fitted either separately or in combination thereof inside airframe insulation set (19-22) attached with the help of flat insulation end section (12, 12a, 12b) in rib attachment area (15) located below lengthwise sides (41, 41a, 41b) of rib (32, 32a, 32b, 32c) and nearby stringer (31). Aforesaid insulation is fastened by fireproof attachment elements (4, 13). In rib attachment area (15), there is through hole (24). Leading-through sleeve and insulation end section (12, 12a, 12b) are arranged in airframe sets (19-22). Aforesaid end section has hole-like recess.
EFFECT: higher anti-fire safety.
