1. A high volume aerodynamic golf club head comprising:
A) a hollow body (110) having a club head volume of at least 400 cc, a face (200), a sole section (300), a crown section (400), a front (112), a back (114), a heel (116), and a toe (118), wherein
i) the hollow body (110) has a bore having a center that defines a shaft axis (SA) which intersects with a horizontal ground plane (GP) to define an origin point; andii) the hollow body (110) has a center of gravity (CG) located:
(a) vertically toward the crown section (400) from the origin point a distance Ycg in a direction orthogonal to the ground plane (GP), and vertically toward the crown section (400) from a horizontal center face plane (HCFP) a distance Vcg in a direction orthogonal to the horizontal center face plane (HCFP);(b) horizontally from the origin point toward the toe (118) a distance Xcg that is parallel to a vertical plane defined by the shaft axis (SA) and parallel to the ground plane (GP); and(c) a distance Zcg from the origin toward the back (114) in a direction orthogonal to the vertical direction used to measure Ycg and orthogonal to the horizontal direction used to measure Xcg; B) the face (200) having a top edge (210) and a lower edge (220), wherein a top edge height (TEH) is the elevation of the top edge (210) above the ground plane (GP) when the high volume aerodynamic golf club head (100) is positioned in a design orientation, and a lower edge height (LEH) is the elevation of the lower edge (220) above the ground plane (GP) when the high volume aerodynamic golf club head (100) is positioned in a design orientation; and C) the crown section (400) having a 12 degree pitched up orientation crown apex (610) and defining a 12 degree pitched up/8 mm drop contour area (CA), wherein;
i) the 12 degree pitched up orientation crown apex (610) is located at the peak height of the crown section (400) when the hollow body is positioned in a 12 degree pitched up orientation that includes an absolute lie angle of 55 degrees, a face angle of 0 degrees, and a pitch angle of 12 degrees up;ii) the 12 degree/8 mm drop contour area (CA) is defined as the cross-sectional area of an intersection of the crown section (400) with an offset plane located at an elevation that is 8 mm below the 12 degree pitched up orientation crown apex (610) and parallel to the ground plane (GP) when the hollow body is positioned in the 12 degree pitched up orientation; D) wherein the hollow body (110) has a projected area of the face portion (Af) of between 9.5 square inches and 11.25 square inches, and wherein the 12 degree pitched up/8 mm drop contour area (CA) is less than 6.5 square inches and greater than the following linear expression:
CA=(−1.5395)*Af+17.625. |
