Abstract:
A method of designing a golf club head, said method comprising:selecting a location for a center of gravity of the golf club head,selecting magnitudes and directions for a set of principal moments of inertia of the golf club head, said principal moments of inertia defining a maximum moment, a minimum moment and an intermediate moment of inertia and being oriented along orthogonal axes intersecting at said location of said center of gravity;orienting a principal axis associated with the maximum moment of inertia such that an inertia loft angle of the golf club head is less than the geometric loft angle of the golf club head; anddistributing mass within said golf club head such that the center of gravity of the golf club head is located at said selected location, and such that the principal moments of inertia of the golf club head have said selected magnitudes and directions.
