The aeroelastic behavior of a blended wing body- (BWB-) type wind-tunnel model is investigated. The design concept, numerical modeling, and experimental procedures are described together with comparisons of numerical and experimental results. The main focus is on aeroelastic response due to static and dynamic control surface deflections. The numerical analysis is performed using a finite element structural model and doublet lattice aerodynamics. The agreement between the predicted and experimental aerodynamic loads and aeroelastic deformations are good overall. However, the investigation shows that the loads due to control surface deflections are slightly overpredicted by the numerical analysis. The results indicate that available numerical methods are capable of predicting aeroelastic behavior of the BWB-type aircraft with reasonable accuracy.
