摘要:
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 certain spin ratios and Reynolds Numbers, and more particularly the golf ball has a low lift coefficient at a high Reynolds Number.

A golf ball (20) having a plurality of standard dimples (33) and a plurality of covered dimples (31) is disclosed herein. Each of the plurality of covered dimples (31) has at least one overhang land area portion (50) that covers a portion of a concavity (55) of the covered dimple (31). A covered region (70) under the overhang land area portion (50) generates eddy currents during the flight of the golf ball (20) which creates greater turbulence at the surface (22) of the golf ball (20) allowing for greater distance.

A golf ball (20) having a plurality of standard dimples (33) and a plurality of undercut dimples (31) is disclosed herein. Each of the plurality of undercut dimples (31) has at least one undercut area portion (50) that extends into a portion of a concavity (55) of the undercut dimple (31). A covered region (70) defined by the undercut area portion (50) generates eddy currents during the flight of the golf ball (20) which creates greater turbulence at the surface (22) of the golf ball (20) allowing for greater distance.

摘要:
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 with dimple diameters of greater than 6.5 percent of the ball diameter and dimples with a profile defined by a catenary curve.
