Application of Divergent Trailing-Edge Airfoil Technology to the Design of a Derivative Wing 892288
The incorporation of divergent trailing-edge (DTE) technology into the design of a derivative wing is pres ented. The structural constraints imposed by the derivative approach will be reviewed with respect to their impact on the wing design. The predicted drag and buffet characteristics, derived using a combination of computational fluid dynamics (CFD) and empirically developed methods, are compared to wind tunnel measured characteristics. Calculated and measured results show a significant improvement in the performance of the derivative wing due to the integration of DTE airfoil technology.
