"This project investigated: the effect of 90 \u00B0 layers on the stability of the wing skin isolated cells with simply supported edges of interregional passenger plane; the influence of the layers order with different reinforcement directions in the laminat on the critical buckling stress of the cells; the effect of curvature, which is characteristic for between-longeron and the bow parts of the upper wing skin, the stability of isolated cells with simply supported edges. Defined the influence of the structure of composite panels on its stability under pure compression with simple support edge and the optimal structure. Were estimated the curvature effect on stability of the composite panels. Were made recommendations about choosing the structure of composite material skin panels of the plane bearing surface"@en .
