ABSTRACT:
A golf clubhead has been multi-angularly streamlined so that it presents reduced aerodynamic drag when swung throughout the entire 120 degrees prior to impact with a golf ball. During this portion of the swing, golfers typically rotate their golf club about the axis of its shaft by up to 135 degrees. During the 120 degrees of swing prior to ball impact, the club is typically accelerated from about 50 MPH to 100 MPH or more. The streamline shape is developed for higher efficiency for air flow encountered at the high speed portion of the swing arc at the expense of reduced streamline efficiency during the slower portion of the swing. The shapes herein conform to U.S.G.A. rules. Allowance is also made in the streamline shape for the non-radial sweep of the shaft during the earlier portion of the swing. In the preferred embodiment, a high strength faceplate is fitted to a low density aerodynamic fairing thereby creating a clubhead combination with a center-of-mass close to the plane of impact. The club shaft is preferably fitted to an extension of this faceplate. Test clubs have exhibited increased driving distance and increased accuracy, believed to be due to higher club speed and reduced perturbation of the club path by air turbulence.
