The mathematical description of a nacelle, body or airfoil having a round nose and pointed aft-end is a continuous but non-analytic function because of the infinite slope at the nose and the corresponding large variations of curvature over the surface. Consequently, a large number of coordinates are typically required to describe the geometry. The general mathematical formulation necessary to describe an airfoil, axisymmetric body or nacelle, is defined in order to develop a "fundamental"doi:10.2514/6.2006-6948 fatcat:irh7rxa5yre3fjymjmc7jjjpba
