METHOD OF MANUFACTURE OF INTRICATE-PROFILE ARTICLES FROM COMPOSITE MATERIALS BY CONTINUOUS WINDING METHOD Russian patent published in 1997 - IPC

FIELD: manufacture of introcate-profile articles, such as aerodynamic load-bearing members (aircraft wings, helicopter blades, air and water propellers, power plants of pumps, compressors, fans, rudders); aircraft manufacture, shipbuilding, automobile manufacture and other industries. SUBSTANCE: method consists in continuous multi-cycle winding of composite material on revolving mandrel from its end to root and vice versa over combined trajectory; each cycle includes four spiral sections, two rectilinear junctions over root end and two circumferential sections smoothly changing from one to other. Starting point of laying the material is shifted in each subsequent cycle relative to similar point of previous cycle in direction of root end; in making the junctions, insert fasteners are simultaneously wound-in. EFFECT: enhanced reliability. 5 cl, 3 dwg
