5/17/2023 0 Comments Thin airfoil theory assumptionsThe distribution function is assumed to take the following form. So rather than considering the strength of point vortices, we consider the strength of the distribution per unit length, γ(s). The vortex distribution along the mean line forms a continuous vorticity sheet. ![]() ![]() However, as it models inviscid flow, there will be no estimate of drag coefficient. This is a standard potential flow modelling technique which will give quick and reasonable estimates of lift coefficient and moment coefficient. ![]() For incompressible, inviscid flow, an aerofoil section can be modelled by a distribution of vortices along the mean line. A simple solution for general two-dimensional aerofoil sections can be obtained by neglecting thickness effects and using a mean-line only section model.
