Abstract
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
Claims17
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.
A golf ball comprising a solid core, a solid cover and an intermediate layer disposed therebetween, wherein the intermediate layer comprises a fluid, wherein the fluid has a viscosity between about 1000 and about 250,000 centipoises.
A golf ball comprising a solid core, a solid cover and an intermediate layer disposed therebetween, wherein the intermediate layer comprises a viscous fluid, wherein the specific gravities of the viscous fluid and the core are within about 3% of each other.
