Abstract:
An aerodynamic golf club head producing reduced aerodynamic drag forces via the curvature of a crown section. At least a portion of the crown section may be composed of low density materials, including nonmetallic materials.

Claim (Index 12):
An aerodynamic golf club head comprising:\n A) a hollow body having a club head volume of at least 400 cc, a face, a sole section, a crown section, a front, a back, a heel, and a toe, wherein the hollow body has a front-to-back dimension of at least 4.4 inches, and a second moment of inertia (MOIx) about a horizontal axis through the center of gravity is at least 2000 g*cm 2 ; B) the face having a top edge and a lower edge, wherein a top edge height is the elevation of the top edge above the ground plane, and a maximum top edge height is at least 2 inches; and C) the crown section having a crown apex located an apex height above a ground plane and having an apex ratio of the apex height to the maximum top edge height, wherein:\n (i) within a front-to-back vertical section through the crown apex and perpendicular to a vertical plane created by a shaft axis, a portion of the crown section between the crown apex and the face has an apex-to-front radius of curvature, and a portion of the crown section between the crown apex and the back of the hollow body has an apex-to-rear radius of curvature, \n (ii) within a heel-to-toe vertical section through the crown apex and parallel to the vertical plane created by the shaft axis, a portion of the crown section above the top edge height has a heel-to-toe radius of curvature; and \n (iii) the crown section has at least two of the following characteristics:\n (a) the apex-to-front radius of curvature in contact with the crown apex is less than 3 inches; \n (b) the heel-to-toe radius of curvature in contact with the crown apex is less than 4 inches; \n (c) the apex-to-rear radius of curvature of a portion of the crown section above the top edge height is less than 3.75 inches; \n (d) the apex-to-rear radius of curvature of a portion of the crown section above the top edge height is greater than 5 inches; and \n (e) the apex-to-front radius of curvature in contact with the crown apex is at least 25% less than a portion of the apex-to-rear radius of curvature located above the top edge height.
