A golf club head including a face defining a loft plane, a rear, and a crown, the crown having a turbulator comprising a plurality of ridges. Each ridge includes a front surface having a first end nearest the face, a second end nearest the ridge apex, and a rear surface nearest the rear portion of the club head. The turbulator is positioned in a forward two-fifths portion of the crown in a front end to a rear end direction. The ridge apex of each ridge is positioned within the first 50% of the ridge length.

Golf club heads with turbulators and methods to manufacture golf club heads with turbulators

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 between the face and the apex, wherein each adjacent pair of crown turbulators is separate and spaced apart to define a space between the adjacent pair of crown turbulators.

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.

Embodiments of golf club heads with apertures and methods to manufacture golf club heads are generally described herein. In some embodiments, a golf club head comprises a face portion, a back portion generally opposite the face portion, a heel portion extending between the face portion and the back portion, a toe portion opposite the heel portion and extending between the face portion and the back portion, and a crown portion extending between the face portion, the back portion, the heel portion, and the toe portion, the crown portion comprising a plurality of crown aperture. The crown portion comprises a first region and a second region, wherein the first region is nearer to the face portion than the second region, the first region and the second region are separated by a bell-shaped curve. The bell-shaped curve is located a distance D1 from the face portion and the second region comprises a recess portion. The plurality of crown apertures is defined within the recessed portion. In some embodiments, the golf club head comprises both metal and fiber-based composite portions. In other embodiments, the golf club head comprises a plurality of sole apertures. Other embodiments may be described and claimed.

Golf club heads with apertures and methods to manufacture golf club heads

A golf club head including a crown, a sole, a face portion defining a loft plane, a rear portion, and a leading edge between the face portion and the crown. The crown comprises a turbulator comprising a plurality of ridges. Each ridge comprises a front surface having a first end nearest the face, a second end nearest the ridge apex, and a rear surface nearest the rear portion of the club head. The turbulator is positioned in a forward two-fifths portion of the crown in a front end to a rear end direction. The golf club head further comprises a plurality of protrusions on the crown, wherein the plurality of protrusions is positioned near the leading edge and extends toward the rear of the golf club head.

Some embodiments include a club head for adjusting vertical spin of a golf ball. Other embodiments of related systems and methods are also disclosed.

A golf club head and a method of manufacturing a golf club head are described herein. The golf club head comprises a club face with a face portion, and grooves positioned on the club face. The grooves each comprise a bottom, a first side wall adjacent the bottom, a second side wall adjacent the bottom, a first top radius adjacent the first side wall, and a second top radius adjacent the second side wall. The club face further comprises a second portion positioned between the face portion, and the first top radius and the second top radius. The second portion of the club face allows for the grooves to appear visually wider to a player, which can provide psychological effects to benefit performance, while still conforming to USGA groove widths standards.
