AERODYNAMIC SURFACE GEOMETRY FOR GOLF BALL

PROBLEM TO BE SOLVED: To provide a golf ball which minimizes a land area which trips an air boundary layer around the golf ball when flying in order to form a turbulent flow required for lengthening a flying distance more. SOLUTION: The golf ball 20 approaching zero land area is disclosed. The golf ball 20 has an inner sphere having a plurality of primary lattice members 40 and a plurality of sub-lattice members 41. Each of the plurality of primary lattice members 40 has an apex and the golf ball 20 of this invention coincides with a requisite for USGA to approve which is a diameter of 1.681 inches. The primary lattice members 40 and the plurality of sub-lattice members 41, which are connected each other, form two or more dual polygons and these are preferably dual hexagons and dual pentagons.
