STABLE-SIZE ENCLOSURE

摘要

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 ""-like flutes. Stringers are made from layers of fibrous material impregnated with polymer binder and arranged on outer surface of ""-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 ""-shape flutes. ^ EFFECT: higher axial size-stability under temperature and vacuum effects. ^ 3 cl, 3 dwg
