| 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 ... |
