Strength and Aeroelastic Structural Optimization of Aircraft Lifting Surfaces using Two-Level Approach

The paper gives brief description of the multidisciplinary design system for aeroelastic and strength optimization of aircraft lifting surfaces. Structural models of two levels are described. Main relationships for analysis of characteristics of static and dynamic aeroelasticity used as constraints in structural optimization are given. The optimization methods used for the optimization are described. The solution of two example problems of optimization under strength and aeroelasticity constraints of lifting surfaces of aircraft illustrates the possibilities of the approach
