Abstract
A golf ball includes an outer land surface and a plurality of dimples formed thereon. The dimples comprise protrusions on the inner surface of the dimple to energize or agitate the airflow over the dimpled surfaces to increase the aerodynamic performance of the golf ball. These protrusions include rotational elements arranged in various configurations and are fully contained within the dimple perimeter and do not extend beyond a chordal plane of the dimple. By improving the aerodynamic of the airflow over the dimpled surface of the golf ball, the outer land surface of the golf ball may remain robust to prevent premature wear and tear on the golf ball.
Claims8
A golf ball having recessed dimples on the surface thereof, wherein at least one dimple is defined by a protrusion formed on an inner surface, the protrusion comprising a plurality of rotational elements whereby a boundary layer of air flowing over the surface of the dimples is energized.
