  • Publication number: 20050032584
    Abstract: A golf club, a driver, designed to provide an inprovement in the accuracy of ball control as club head speeds are increased from 100 miles per hour to the level of a semipro at 120 miles per hour. Most forces on the club head increase as the square of the velocity, representing a forty four percent increase. A detailed analysis has been made of forces generated during the collision of the ball and club head and their effect on trajectory of the ball. The design proposed greatly reduces the aerodynamic drag of the clubhead, increases the allowable tolerance to angular misalignment of the club striking face from two degrees to ten degrees and reduces the torque that twists the club head causing an angular misalignment prior to contact with the ball.
