Unsteady Viscous Thin Airfoil Theory,

Abstract

During the last three years considerable progress has been made in the prediction of unsteady airloads on profiles in transonic flow, but prediction is still limited to potential inviscid flow. New analytical developments, and comparison with experimental results, need the introduction of the coupling between the inviscid flow and the boundary layer. Dr Yates, in this publication, proposes an original approach to the problem which permits a first calculation of boundary layer effects. He derives a new kernel of the lifting surface integral equation which takes into account shear flow effects in the boundary layer.
