A Simple Model of Vortex Flow Past a Slender Elliptic Cone at Incidence

Abstract

The single line-vortex model of the separated flow past a slender pointed body of revolution at incidence is extended to elliptic cones, within the framework of slender-body theory, and maintaining lateral symmetry in the flow. An analytical solution is found for the limiting behavior of the model when the vortices are weak. The angle of incidence above which solutions exist is found as a function of the axis ratio of the elliptic cross-section and the postulated location of the separation lines.
