Abstract
A dimple pattern for a golf ball with multiple sets of dimples is disclosed herein. Each of the multiple sets of dimples has a different diameter. A preferred set of dimples is twelve different dimples. The dimples may cover as much as eighty-seven percent of the surface of the golf ball. The unique dimple pattern allows a golf ball to have shallow dimples with steeper entry angles. In a preferred embodiment, the golf ball has 382 dimples covering ninety percent of the surface.
Claims11
A golf ball comprising:
- a core composed of a polybutadiene material;
- and
- a cover encompassing the core, the cover composed of an ionomer material, the cover having a surface including at least eleven sets of dimples covering at least 87% of the surface, each set of dimples having a different dimple diameter than any other set of dimples, the different dimple diameters ranging between 0.124 inch and 0.186 inch, and at least one set of dimples includes a first dimple having a first entry radius and a second dimple having a second entry radius, the first entry radius differing from the second entry radius.
A golf ball comprising:
- a core composed of a polybutadiene material;
- a cover encompassing the core, the cover composed of an ionomer material, the cover having a surface including at least eleven sets of dimples covering at least 87% of the surface, each set of dimples having a different dimple diameter than any other set of dimples, the different dimple diameters ranging between 0.124 inch and 0.186 inch, and at least one set of dimples includes a first dimple having a first entry angle and a second dimple having a second entry angle, the first entry angle differing from the second entry angle.
golf ball comprising:
- a core composed of a polybutadiene material;
- and
- a cover encompassing the core, the cover composed of an ionomer material, the cover having a surface including at least eleven sets of dimples covering at least 87% of the surface, each set of dimples having a different dimple diameter than any other set of dimples, the different dimple diameters ranging between 0.124 inch and 0.186 inch, wherein the golf ball has a lift coefficient greater than 0.19 at a Reynolds number of 70,000 and 2000 rpm, and a drag coefficient less than 0.232 at a Reynolds number of 180,000 and 3000 rpm.
