FIELD: transport.
SUBSTANCE: invention relates to aircraft engineering, particularly, to aircraft fuel tank. Fuel tank comprises body two gas supercharge and fuel feed devices. Extra shell is fitted with clearance relative to the body there inside. Cutouts are made in said shell opposite said gas supercharge and fuel feed devices. Note here that said clearance is selected from the relationship: 0,002·D≤δ≤0,145·D, where δ is clearance between tank body inner surface and shell; D is tank body ID.
EFFECT: decreased weight, increased volume, decreased fuel heating.
