Theoretical Investigation of Dynamic Stall Using a Momentum Integral Method,
Abstract
An analytical study into the gust response of an airfoil is presented. The momentum-integral equation for steady flow is extended into the airfoil that experiences a constant-rate-of-change of angle-of-attack gust. The von Karman-Pohlhausen method of integration is successfully modified to incorporate the additional transient flow terms; the equation of closure necessary to do this is also presented. Finally, computation of the flow about a Joukowski airfoil using the new equations is performed and the results are presented and discussed. It is shown that these results are in agreement with existing experimental data.
