This thesis contains discussion, theory and program code for a computational fluid dynamics (CFD) model of a wing of arbitrary planform. The model assumes incompressible, inviscid, irrotational flow. The program computes forces acting on the wing by modeling the flow with a set of horse shoe vortex elements. It models the flow over an arbitrary wing using two solutions. One solution is the ideal lift, associated with a cambered and twisted wing. The other solution is the additional lift associated with a flat wing. The program computes wing camber and twist using an elliptic loading distribution. The thesis includes the FORTRAN source code, a separable User's Manual for the VORTEX program, discussion of the theory applied in the model, and instructions for operating the program. It shows a sample wing planform with tabular and graphic results. The thesis also discusses two other CFD models based on circulation (T) and pressure difference (ΔC(p)). It presents some of the problems and solutions in grid generation.
