409 Simultaneous measurement of aerodynamic 4-components forces on spinning golf ball in wind tunnel(1)

Abstract

Highly spinning golf ball aerodynamics is studied by wind tunnel experiments. To estimate a precise trajectory of golf ball 3-D flight, in this stage, more accurate and simultaneous measurement to confirm 4-components of aerodynamic forces on spinning golf ball is needed. We had challenged this problem with freely rotation and it's naturally decaying golf ball experiment system in wind tunnel flow.
