FIELD: transport.
SUBSTANCE: stable-size enclosure comprises metal cylindrical-shape enclosure, stringers oriented along enclosure lengthwise axis and face metal frames. Proposed enclosure has annular "П"-like flutes. Stringers are made from layers of fibrous material impregnated with polymer binder and arranged on outer surface of "П"-like flutes. Stringers feature negative thermal coefficient of linear expansion along enclosure lengthwise axis and are mechanically coupled with its skin in sections where it adjoins annular "П"-shape flutes.
EFFECT: higher axial size-stability under temperature and vacuum effects.
