FIELD: manufacture of aerodynamic and hydrodynamic streamlined articles. SUBSTANCE: solid sections of aerodynamic streamlined objects (load-bearing members) are formed. To this end, inner load-bearing layer is formed by spiral winding of fiber pregreg on mandrel. Then interlayer filler is placed at part of formed inner load-bearing layer and outer layer is formed by spiral winding of fiber pregreg on inner load-bearing layer formed before, after which interlayer filler is placed. Then row of solid sections of aerodynamic streamlined article which are load-bearing members which bear secondary load is formed. Row of sections thus formed carry main and secondary loads is arranged in definite sequence for forming aerodynamic streamlined article. Then, at least one layer of fiber pregreg is spirally wound on aerodynamic streamlined article thus formed which is subjected to polymerization at high temperature. Then mandrels are removed. EFFECT: enhanced reliability. 9 cl, 9 dwg |
