Title:
GOLF CLUB HEADS WITH TURBULATORS AND METHODS TO MANUFACTURE GOLF CLUB HEADS WITH TURBULATORS
Document Type and Number:
Japanese Patent JP2019111369
Kind Code:
A
Abstract:
To provide golf club heads with turbulators and methods to manufacture golf club heads with turbulators.SOLUTION: A golf club head 100 comprises a turbulator 300. The turbulator 300 energizes a boundary layer on a crown by generating turbulence in the boundary layer. The turbulator 300 is located on the crown at a constant or variable distance 301 downstream of the leading edge 112 and may extend from a hosel 114 or a heel end 104 to a toe end 106. The turbulator 300 provides a plurality of projected surfaces in discrete or continuous form on the surface of the crown at a prescribed height. When the air flowing over the crown encounters the projected surfaces of the turbulator 300, the air trips and becomes turbulent inside the boundary layer to energize the boundary layer.SELECTED DRAWING: Figure 4
