Abstract : Two areas of study are considered: (1) the aerodynamic field around spinning, smooth spheres, and (2) the preparation of software for the solution of flight dynamics problems on programmable desktop computers. In the first area, the surface velocity components are determined as a function of physical and dynamic variables by superposition of inviscid, incompressible uniform and spinning flows. The result is a very simplified picture of the pressure distribution and streamline shapes over the sphere. In the second area, three programs for the solution of a certain class on nonlinear aerodynamic problems are presented. These are written for the Wang 700 computers as well. The programs provide solutions for nonlinear equations.
