Summary

The influence of the free vortex sheets on the pressure distribution of delta-wings is analysed with a higher order panel-method. The bounded vortex sheets are represented with isoparametric elements in order to get a continuous doublet distribution without singular vortex-lines for the wing itself. The free vortex layers, which detach already at small angles of attack from the sharp edges of the delta-wings, are paneled along the vortex-lines specified by the wing doublet distribution. With two independent geometry parameters for each panel as used in this “vortex-line adjusted panel-method” a successful modeling of the free vortex sheets is possible.
