Abstract
The present disclosure is directed to golf balls having improved aerodynamic performance due, at least in part, to the selection of the plan shapes of the dimples thereon. In particular, the present invention is directed to a golf ball that includes at least a portion of its dimples having a plan shape defined by a Clausen function of order 2 mapped along a simple closed path. Additionally, the present invention provides methods for designing dimples having a plan shape defined by a Clausen function of order 2 mapped along a simple closed path.
Claims15
A golf ball having a spherical surface and comprising a plurality of dimples on the spherical surface,
- wherein at least a portion of the plurality of dimples have a non-circular plan shape defined by a periodic function along a simple closed path that is selected from:
- a circle, an ellipse, a polygon, or an arbitrary closed curve,
- wherein the periodic function is a Clausen function of order 2.
