In this investigation some aspects of design, production and experimental verification of composite structural elements are considered. Attention is focused on strength analysis of composite structures with application to helicopter main rotor blades HT-40. Special attention in this consideration is focused on strength analyses of composite structures with application on helicopter main rotor blades. For that purpose strength analysis of helicopter main rotor blade segment made from composite materials is considered using finite element method (FEM) and experimental verifications. In this study honeycomb sandwich structure is considered. Just honeycomb sandwich structural element is modeled using shell finite elements. For structural analysis of this type construction Msc/NASTRAN software code is used. For precise determination of aerodynamic loads of main rotor blades in this consideration the complete helicopter is modeled using CFD numerical simulation including main rotor, tail rotor and fuselage. To validate computation procedure in this consideration the honeycomb structural element is experimental tested. The results of numerical simulations are compared with own experiments.
