摘要:
A golf ball having at least three types of dimples arranged in a specific distribution pattern has improved aerodynamic symmetry and offers consistent flying performance. Three phantom orthogonal great circles are drawn on the spherical surface of the ball to define eight spherical regular triangles, and phantom perpendiculars are extended from the three apexes of each spherical regular triangle to the opposite sides to divide the spherical regular triangle into six equal spherical right triangles, thereby dividing the entire spherical ball surfaces into 48 equal spherical right triangles.dimples are arranged on every two adjoining spherical right triangles such that the dimples are in axial symmetry with respect to the common side of the two adjoining spherical right triangles and the dimples do not intersect the great circles.
