Single-Pass Method for the Solution of the 2-D & 3-D Inverse Potential Problemtions of the grid lines, after the flow field has been determined. The 2-D case is treated as a particular case of the general 3-D one. The method has been applied to both 2-D and 3-D reproduction cases of the present workshop with very satisfactory results.

Contribution to Problems T4 and T6 Finite Element GMRES and Conjugate Gradient Solversf airfoils represented by cubic splines and operating at subsonic and transonic conditions. It is shown that the number of iterations has been multiplied by three between the subsonic and the transonic case. For the optimization problem, the drag objective function is penalized to take into account

Wing Design with a 3D-Subsonic Inverse Panel Method: ’design patches’, whose surface is derived from given pressures and ’analysis patches’, whose pressures are derived from given surface. To solve such ’mixed’ problems the panel code is embedded into an iteration loop, which minimizes the sum of squared pressure deviations. The geometry representat

A Residual Correction Method Applied to 2D Multi-Point Airfoil Design and 3D Single-Point Wing Desigd is based on full-potential theory and minimizes a cost function weighting the deviations from specified target pressure distributions for each design condition in a least squares sense. Deviations from specified target pressure distributions (residuals) are translated into airfoil geometry correct

Aerodynamic Shape Optimization Using Automatic Adaptive Remeshingzed by the Finite Element Method. A suitable and very general technique for the parametrization of the optimization problem using B-splines to define the boundary is first presented. Then, mesh generation using the advancing front method, the estimation of error and the mesh refinement criterion are
