METHOD OF PRODUCTION OF TUBE OF LAMINATED COMPOSITE MATERIAL WITH HELICAL RIGHT-ANGLED GROOVE AND TUBE OF LAMINATED COMPOSITE MATERIAL WITH HELICAL RIGHT-ANGLED GROOVE Russian patent published in 1998 - IPC

FIELD: applicable in precise-action spin-stabilized signal or meteorological rockets. SUBSTANCE: square- section screw plate is installed on a cylindrical mandrel, then internal layer is applied forming a screw right-angled crimp, preliminarily formed inserts in form of triangular- section strips are laid close to strip ledges and to cylindrical surface of internal layer, and then rest layers of reinforcing casing are applied forming a multilayer reinforcing casing. Internal layer of tube reinforcing casing is furnished with a screw right-angled crimp with a helical right-angled groove and with two triangular-section strips fastened to them and reinforcing casing. EFFECT: enhanced strength of tube with a high stiffness of walls of its helical groove. 9 cl, 10 dwg
