Abstract
Official abstract text for this publication.
The present invention 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 low frequency periodic functions along a closed simple path. In addition, the present invention provides methods for designing dimples having a plan shape defined by a low frequency periodic function along a closed simple path.
First claim
Opening claim text (preview).
What is claimed is: 1. A golf ball having a generally 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 low frequency periodic function mapped along a circular simple closed path resulting in the following function: Q ( x )= F path ( l,scl,x )* F periodic ( s,a,p,x ) where F path is a circular function of length l, with scale factor scl, defined along the vertices x; and F periodic is selected from a periodic square wave function defined by the equation: f ( x ) = s + a π ( sin ( π px ) + 1 3 sin ( 3 π px ) + 1 5 sin ( 5 π px ) + 1 7 sin ( 7 π px ) ) and a periodic sawtooth function defined by the equation: f ( x ) = s - a π ( sin ( π px ) + 1 2 sin ( 2 π px ) + 1 3 sin ( 3 π px ) + 1 4 sin ( 4 π px ) )
