Control of Unsteady Aerodynamic Forces

Abstract

The aerodynamic properties of an airfoil under unsteady conditions are very different from ones in steady conditions because the vortex generated by unsteady separation greatly modifies the loading on the wing. In this study, a fundamental approach was taken to investigate the lift and the velocity field of unsteady airfoils. Keywords: Airfoil unsteady water channels, Delta wings, Lift, Flow visualization.
