    • A high volume aerodynamic golf club head with a club head volume of at least 400 cc and a front-to-back dimension of at least 4.4 inches producing a face-on normalized aerodynamic drag force of less than 1.5 lbf when exposed to a 100 mph wind parallel to the ground plane and oriented at the front of the club head. The club head has a crown section having a crown apex located an apex height above a ground plane, wherein a portion of the crown section between the crown apex and the face has an apex-to-front radius of curvature that is less than 3 inches. An apex ratio of the apex height to a maximum face top edge height is at least 1.13. The apex height and location of the crown apex obtain desirable airflow reattachment close to the face and improve airflow attachment to the crown section.
    • 具有至少400cc的球杆头体积和至少4.4英寸的前后尺寸的大体积空气动力学高尔夫球杆头当暴露于100mph时产生小于1.5lbf的正面空气动力学牵引力 风向平行于地平面并朝向球杆头前方。 球杆头具有冠部,冠部顶点位于地平面以上的顶点高度,其中冠部冠部和面部之间的顶部部分的一部分具有小于3英寸的顶点到前面的曲率半径 。 顶点高度与最大面顶部高度的顶点比值至少为1.13。 冠顶的顶点高度和位置获得了靠近脸部的所需气流重新附着,并改善了与冠部分的气流附着。
