Golf ball with improved flight performance
View Patent ↗A golf ball with aerodynamic coefficient magnitude and aerodynamic force angle, resulting in improved flight performance, such as increased carry and flight consistency regardless of ball orientation. In particular, the present invention is directed to a golf ball having increased flight distance as defined by a set of aerodynamic requirements, at particular spin ratios and Reynolds Numbers. The invention is also directed toward golf balls having high spin decay rates during the first second of flight that yields improved flight performance and longer ball flight.
1. A golf ball comprising a solid core, a solid cover and an intermediate layer disposed therebetween, wherein the intermediate layer comprises a fluid, such that after being impacted by a golf club the rate of spin decay is greater than 4% during the first second after impact, wherein the intermediate layer further comprises a foamed polymer.
2. The golf ball of claim 1 , wherein the foamed polymer comprises an open-cell foamed polymeric material.
3. The golf ball of claim 2 , wherein the open-cell foamed polymeric material has a porosity between about 30% and about 70%.
4. The golf ball of claim 2 , wherein the open-cell foamed polymeric material has a permeability of at least about 50% of the flow rate of the fluid in the intermediate layer without the foamed polymer.
