FIELD: machine building, applicable for manufacture of launching tubes for rockets with twisting of them by offset driving knife components. ^ SUBSTANCE: the tube has a heavy-duty shell and a polymeric layer for cutting-in of the rocket knife components. The inner surface of the polymeric layer is made with reduction of its radius from the tube rear end face in the direction of rocket motion at its launching. The character of reduction is determined by the power dependence. ^ EFFECT: enhanced close grouping of shots due to the reliable twisting of the rocket. ^ 2 dwg |
