This paper describes an experimental study on effect of dimple number on flying characteristics of golf ball. This study clarifies the flight characteristics of the stationary spheres to the number of dimples and the depth of dimple as the basis study of the flight characteristics of the golf ball. Therefore, the surface of sphere of 42.6mm in diameter arranges 184∿328 dimples regularly. And in the wind velocity in the range from 15m/s to 45m/s, it measured drag and lift of these spheres in 15m/s intervals. Then, it found that the number of dimples and the depth of dimple gave the drag characteristic a big influence after doing the comparison and the examination of the measurement data. And also, to observe a separation point of spheres, it experimented in the visualization by the oil film method and static pressure distribution.
