Keywords: aeroelasticity, composite wing, two-model approach

The results of new algorithm’s validations for composite wing optimization procedure taking into account constraints on structure elasticity characteristics. Using the solution of the analytical beam model of lateral wing to form additional stiffness constrains for classical FEM-model optimization procedure. Results of calculation for non-traditional airframe composite structures.
