Abstract

A golf club head includes a crown surface extending between the face, the rear, the heel and the toe of the golf club head. A highest point on the surface of the crown defines an apex. The golf club head also includes a plurality of crown turbulators projecting from the surface of the crown. Each adjacent pair of crown turbulators is separate and spaced apart to define a space between the adjacent pair of crown turbulators, and each crown turbulator extends between the heel and the toe to define a width and extending between the face and the rear to define a length, which is substantially greater than the width. At least a portion of at least one crown turbulator is located between the face and the apex. The space between each adjacent pair of crown turbulators is substantially greater than the width of each of the adjacent pair of crown turbulators that define the space.

3. The golf club of claim 1, wherein the plurality of turbulators are oriented relative to the face in generally the same direction.

4. The golf club of claim 1, wherein each turbulator is oriented relative to the face in generally a first direction and an adjacent turbulator is oriented relative to the face in generally a second direction different from the first direction.

5. The golf club of claim 1, wherein the length of each turbulator is oriented relative to the face at an angle of greater than 0°

and less than 90°

.

6. The golf club of claim 1, wherein the length of each turbulator is oriented relative to the face at an angle between around 20°

and around 70°

.

7. The golf club of claim 1, wherein the space between each adjacent pair of turbulators is defined by a section of the surface of the crown.

8. The golf club head of claim 1, further comprising a plurality of sole turbulators disposed on the sole surface.

9. The golf club head of claim 8, wherein each of the sole turbulators is defined by a groove in the sole surface having a width and a length substantially greater than the width.

10. The golf club head of claim 8, wherein at least one of the sole turbulators is located in a portion of the sole surface between the heel and a centerline extending from a center of the face to the rear.

11. The golf club head of claim 10, wherein the at least one sole turbulator has a first end located near the heel and extending generally toward the toe to a second end.

12. The golf club head of claim 8, wherein at least one of the sole turbulators is located in a portion of the sole surface between the toe and a centerline extending from a center of the face to the rear.

13. The golf club head of claim 12, wherein the at least one sole turbulator has a first end located near the face or the toe and extending generally toward the toe to a second end.

14. A golf club head comprising:

a face, a rear opposite to the face, a heel, a toe opposite to the heel, a crown having a crown surface extending between the face, the rear, the heel and the toe, and a sole opposite to the crown and having a sole surface extending between the face, the rear, the heel and the toe;

a first plurality of sole turbulators defined by grooves disposed in a portion of the sole surface between the heel and a centerline extending from a center of the face to the rear, at least one sole turbulator of the first plurality of sole turbulators extending from near the heel in a direction generally toward the toe; and

a second plurality of sole turbulators defined by grooves disposed in a portion of the sole surface between the toe and the centerline on the sole surface, at least one sole turbulator of the second plurality of sole turbulators extending from near the face or the toe in a direction generally toward the rear;

wherein a width of at least one sole turbulator of the first plurality of sole turbulators or the second plurality of sole turbulators varies along a length of the at least one sole turbulator.

15. The golf club head of claim 14, further comprising a plurality of crown turbulators disposed on the crown.

16. The golf club head of claim 15, wherein at least a portion of at least one crown turbulator is located between the face and an apex defined by a highest point on the surface of the crown.

17. The golf club head of claim 15, wherein each adjacent pair of crown turbulators is separate and spaced apart to define a space between the adjacent pair of crown turbulators, and wherein each space is substantially greater than a width of each of the adjacent pair of crown turbulators that define the space.

18. The golf club head of claim 14, wherein each of the plurality of first sole turbulators comprises a first end and a second end, and wherein the first end and the second end define a line extending in the same general direction as the heel.

19. The golf club head of claim 14, wherein the lengths of at least two sole turbulators of the first plurality of sole turbulators or the second plurality of sole turbulators are different.

20. The golf club head of claim 14, wherein at least two sole turbulators of the plurality of first sole turbulators or the plurality of second sole turbulators are generally parallel.

21. The golf club head of claim 14, wherein at least two sole turbulators of the plurality of first sole turbulators or the plurality of second sole turbulators are generally non-parallel.

22. The golf club head of claim 14, wherein the lengths of the plurality of first sole turbulators progressively increase in a direction extending from the heel to the toe.

23. The golf club head of claim 14, wherein the lengths of the plurality of second sole turbulators progressively increase in a direction extending from the face or the toe to the rear.

24. A method for providing turbulators on a club head comprising:

providing a club head comprising a face, a rear opposite to the face, a heel, a toe opposite to the heel, a crown having a crown surface extending between the face, the rear, the heel and the toe, and a sole opposite to the crown and having a sole surface extending between the face, the rear, the heel and the toe, wherein a highest point on the surface of the crown defines an apex;
