A12 Development of air suspended balance for sports ball aerodynamic force measurement
Details
High quality measurements of aerodynamic forces acting on golf ball under high speed rotation are very important for correct evaluations of golf ball aerodynamics. More than 3% longer distance of 300 yards ball flight may be achieved by improvements of aerodynamic performance of ball dimple patterns. But in this stage, these precise evaluations to measure aerodynamic forces are impossible because of racks of methods and techniques. We are trying this problem by air suspension balance method. Some valuations of atmospheric and supplying air pressure change effects on air force of Z-direction measurement of wind tunnel experiments are studied by introducing cancelling technique by using a dummy balance.
