Abstract
A golf club head includes a crown surface having an apex at a highest point and extending between the face, the rear, the heel and the toe of the golf club head. The golf club head also includes a plurality of crown turbulators projecting from the surface of the crown and located at least partially between the leading edge and the apex, wherein the height of each turbulator decreases from the leading edge toward the rear portion.
Claims19
A golf club head comprising:
- a face portion defining a loft plane;
- a rear portion opposite to the face portion;
- a heel portion comprising a heel end;
- a toe portion opposite the heel portion comprising a toe end;
- a sole portion defining an imaginary centerline that extends from a face center portion to the rear portion;
- a crown portion;
- a leading edge portion positioned between the face portion and the crown portion;
- the leading edge portion defining a leading edge plane forming a leading edge angle with the loft plane;
- and
- an apex positioned at a highest point on the crown portion;
- an x-axis extending through a center of the face portion;
- wherein the x-axis is parallel to the face portion;
- a plurality of crown turbulators projecting outwardly from the crown portion positioned between the leading edge portion and the apex;
- each crown turbulator extending between the face portion and the apex to define a turbulator length;
- each crown turbulator extending a distance at least partially between the heel portion and the toe portion to define a turbulator width;
- wherein the turbulator length is substantially greater than the turbulator width;
- each crown turbulator extending outward from the crown to define a turbulator height;
- each crown turbulator having a turbulator front portion defining a portion of the crown turbulator closest to the face portion;
- the turbulator front portion of the crown turbulator being at least partly located on the leading edge portion and between the leading edge plane and the rear portion;
- wherein each of the plurality of crown turbulators is oriented at an identical oblique angle between 20 and 70 degrees to the leading edge portion;
- and
- wherein the sole portion further comprises a first and second plurality of grooves formed as depressions on a surface of the sole portion;
- wherein the first plurality of grooves is located between the imaginary centerline and the heel end;
- and
- wherein the second plurality of grooves is located between the imaginary centerline and the toe end.
