The surface of a golf ball is covered with numerous dimples to increase the flying distance. It is known that it is important to indicate the state of these dimples in terms of occupancy and volume ratio. Past studies have also shown that the conical shape has the lowest drag coefficient when the base shape of the dimple is changed to a cone or a conical base and the drag force is measured at no-rotation. Therefore, in this study, lift and drag force measurement experiments during rotation are conducted in a wind tunnel using model balls with dimple base shapes that are not only spherical, but also conical or conical in shape. Then, flight trajectory simulations will be performed with the obtained results to clarify the effects of dimple occupancy, volume ratio, and base shape. Then, we will discover the items that are particularly important for designing the most flying balls.
