  • Patent number: 8608587
    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.
