# Unsteady aerodynamics of porous aerofoils

@article{Baddoo2019UnsteadyAO, title={Unsteady aerodynamics of porous aerofoils}, author={P J Baddoo and Rozhin Hajian and J. W. Jaworski}, journal={ArXiv}, year={2019}, volume={abs/1911.07382} }

We extend unsteady thin aerofoil theory to model aerofoils with generalized chordwise porosity distributions. The analysis considers a Darcy-type porosity law where the seepage velocity through the aerofoil is linearly related to the local pressure jump across the aerofoil surface. Application of the Plemelj formulae yields a singular Fredholm--Volterra integral equation which does not admit an analytic solution. Accordingly, we develop a numerical solution scheme by expanding the bound… CONTINUE READING
