Abstract: This paper is a sequel of part I. Here, thin airfoil theory for thickness and lifting problems are presented in terms of velocity components due to two dimensional source and vortex distributions. Flows around bodies of revolution are also treated using three dimensional sources and effects of small angle of attack are considered using cross flow analysis. Low and high aspect ratio wings are studied with different approximations. Viscous effects are included using velocity/vorticity formulation as well.

Keywords: thin airfoils; slender bodies; slender wings; lifting line theories; Blasius solution; boundary layer equations; viscous-inviscid interaction; velocity-vorticity formulation; zonal approach; basic aerodynamics; incompressible fluid flow.
