FIELD: plastic metal working; forging and stamping processes for production of long-cut panels with one-sided stiffeners; aircraft manufacture. SUBSTANCE: proposed method includes preliminary molding of initial blank, extruding stiffeners in this blank and final molding by applying working force at angle to initial blank. This angle is varying. Angle is decreased to obtuse angle during preliminary molding and extruding stiffeners and to right angle during final molding. Stiffeners are extruded longitudinally and transversely. Magnitude of change of angle of applying working force is similar at all three stages of deforming. EFFECT: extended functional capabilities. 2 cl, 1 dwg
