Abstract

An approach for estimation of wing deformations based on mathematical model of body with variable density is proposed. The approach is implemented in the software tool coupling aerodynamic and deformation analysis modules. The results of parametric study for a number of wings with different geometrical parameters are presented. It is shown, that significant reduction in structural mass can be achieved by accounting wing deformation on early design stages.
