Abstract
A golf ball having an outside surface with a plurality of dimples formed thereon. The dimples on the ball have a cross-sectional profiles formed by a catenary curve. Shape constants in the catenary curve are used to vary the ball flight performance according to ball spin characteristics and player swing speed.
Claims5
A golf ball having a plurality of recessed dimples on the surface thereof, wherein at least one dimple is defined by the revolution of a Catenary curve, wherein the Catenary curve is defined by hyperbolic cosine function in the form of:
- Y = d ( cosh ( a x ) - 1 ) cosh ( a r ) - 1
- wherein:
- Y is the vertical distance from the dimple apex,
- x is the radial distance from the dimple apex,
- a is a shape constant,
- d is the depth of the dimple, wherein the depth is about 0.025 inches, and
- r is the radius of the dimple, wherein the radius is about 0.05 inches.
