Generating Airplane Wings for Numerical Simulation and Manufacturing

We describe an algorithm for automated generation of multi-parted airplane wings from a cross-section given by a point cloud and the top view of the wing. The relative thickness of the wing (thickness/chord) can be varied from section to section. A rounded tip with two design parameters and GC1-continuity at the crossing to the wing is automatically computed. Constrained approximation and fairing lead to a very smooth geometry especially suited for wind tunnel experiments and numerical simulation. A mounting unit with GC1 fillets to the wing and a simplified half of a fuselage are computed, too. The geometries of those can be modified by changing only a few significant parameters.
