Abstract:

The incorporation of wingbody and viscous flow effects into a directinverse transonic analysisdesign method is described. Slender body theory is used to modify the transonic potential flow solver used in the analysisdesign procedure to account for the effects of a fuselage on the flow characteristics of a wing in transonic flow. Viscous effects were incorporated using a modified two dimensional turbulent boundary-layer program. In addition, a method for enforcing a desired trailing edge thickness during the inverse design process is presented. Results are presented that confirm the accuracy of the method for both analysis and design modes. Keywords Transonic flow analysis Inverse wing design Computational aerodynamics Finite differences.
