Combined Direct/Inverse Three Dimensional Transonic Wing Design with Viscous and Wing/Body Effects. Volume 1. Description of Design Method and Results.

Abstract

The incorporation of wing/body and viscous flow effects into a direct/inverse transonic analysis/design method is described. Slender body theory is used to modify the transonic potential flow solver used in the analysis/design 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.
