ABSTRACT

Even the availability of wind tunnels after the turn of the century did little to spur research. This was at least partly due to the technical difficulty of supporting a spinning object in the tunnel, without interfering with the airflow, and simultaneously measuring the aero-dynamic forces acting on it. Nevertheless, the importance of the subject demanded a practical solution which, until recently, was unavailable. Towards this end, a program was defined with the objective of using modern technology to develop a golf ball aerodynamic testing system capable of producing data which is free of support interference effects, and doing so with a minimum of human intervention and labor.
