FIELD: transport.
SUBSTANCE: meshed cover in the form of rotation body from composite materials includes spiral and circular ribs comprised of layers repeated throughout the cover wall thickness of the systems of crossing spiral and circular strips. Inclined strip passages between circular strips are equally offset relative to each other in circumferential and spiral directions and are made in the form of one family of congruent continuous circular zigzag-shaped spirals located along circular surfaces, which is common to circular surfaces of layers of the systems of crossing spiral and circular strips. Tops of zigzags are adjacent to circular strips of circular ribs crossing in the gap between them with spiral strips or spiral and circular strips of spiral and circular ribs correspondingly so that circular zigzag-shaped ribs are formed and mainly arranged on cover ends.
EFFECT: increasing rigidity, improving reliability and decreasing the weight of the design.
