Golf club with aerodynamic features on club face
First Claim
Patent Images
1. A golf club head comprising:
- a ball-striking face comprising a milled surface;
a crown extending back from the face when the club head is at address;
a sole extending back from the face to meet the crown;
a hosel extending upwards from a heel side of the club head; and
a plurality of aerodynamic features disposed on the face, each aerodynamic feature defining an indentation or protrusion relative to an adjacent portion of the face, having a relief measurable along an axis orthogonal to the face, and having an arc shape when viewed from an axis orthogonal to the face, all of the plurality of arc-shaped aerodynamic features on the entire face are positioned concentrically about a center point of the face, wherein when the golf club head is swung, the plurality of aerodynamic features disrupt air flow over the club head away from the center point, thereby reducing drag.

Abstract
The invention provides golf club heads having aerodynamic features that disrupt air flow over the face when the club is swung. The features are milled into the face of the club head, including curved faces found in wood-type club heads. During a swing, the features cause the boundary layer to separate at a point closer to the rear of the club head during a swing, resulting in reduced drag. The invention also provides golf club heads with faces having a central region of symmetrical surface roughness. The symmetrical roughness in the central region of the face of wood-type club heads allows for shots with less spin and greater distance.
