FIELD: rocketry. SUBSTANCE: fuel tank consists of shell with stiffening members with pipe line 2 mounted on its surface and secured in end units. Pipe line is additionally enclosed in intermediate attachment units for axial displacement and is rigidly secured in one of sections between ends to wall of tank. End attachment units are made in form of bellows compensators 14 with pipe lines mounted in them telescopically; intermediate attachment units are made in form of movable brackets with sliding members 5 which are rigidly secured to pipe lines by means of clips. Dome with lateral surface of aerodynamic form is dusted with polymer material on wall of tank 1 on side of lateral surface of pipe line. EFFECT: retaining of load-bearing capacity of fuel tank due to self- adjustment of axial displacement of pipe line in carrying hot gas through it. 2 cl, 5 dwg
