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 desk-top 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 non-linear aerodynamic problems are presented. These are written for the Wang 700 computers as well. The programs provide solutions for non-linear equations.
