FIELD: reinforced high internal pressure shells. SUBSTANCE: proposed shell has load-bearing framework with cylindrical section, end convex bottoms and flanges in pole holes. Framework is provided with combination of groups of layers of spiral and circular tapes oriented in spiral and circumferential directions by unidirectional high-modulus filament which are fastened by means of polymer binder. Housing is lined with protective coat. Flange and inner surface of bottom are provided with circular surfaces at rectilinear generatrix of minimum radius equal to radius of pole hole and maximum radius equal to rp.h+(rfl-rp.h).(0,25/0,9), where rp.h is radius of pole hole and rfl is maximum radius of flange. EFFECT: enhanced strength of shell. 6 cl, 4 dwg |
