Keywords: composite materials, airframe structures, stress analysis, multidisciplinary approach

A new approach for structure strength and weight analyses at initial stage of designing is considered and validated. The approach is based on a general-purpose principle of multilevel modeling of airframe structure which enables to improve significantly an accuracy of strength and weight predictions for composite structure analysis
