Abstract

In this paper, a practical application of the unsteady Kutta-Joukowski theorem to a higher-order potential flow method is developed and discussed. The formulation of the unsteady version of the Kutta-Joukowski theorem is compared with a pressure integration on a flat plate in order to assess the origins of the non-circulatory term. The approach is verified through comparison with classical unsteady thin-airfoil solutions for the lift response to a sharp-edged gust a sinusoidal gust. Finally, the approach is used to predict the unsteady lift response of a propeller-wing system and the results are compared with a fully unsteady Reynolds-Averaged Navier Stokes analysis.
