Method for predicting a golfer's ball striking performance
First Claim
1. A method for predicting a golfer'"'"'s ball striking performance, the method comprising:
- determining a plurality of pre-impact swing properties for the golfer based on the golfer'"'"'s swing with a first golf club, the plurality of pre-impact swing properties including an impact location and an angular velocity, a linear velocity and an orientation of a golf club head;
generating a plurality of ball launch parameters from a plurality of club head properties of the first golf club, a plurality of ball properties of a first golf ball, and the plurality of pre-impact swing properties, the plurality of club head properties including a plurality of face properties and a plurality of mass properties, the plurality of ball properties including a mass, a radius, a moment of inertia and a coefficient of restitution of the golf ball;
imputing into a trajectory code the plurality of ball launch parameters, a plurality of first atmospheric conditions, and a plurality of lift and drag properties for the first golf ball; and
generating a predicted performance from the trajectory code of the first golf ball if struck with the first golf club by the golfer under the first atmospheric conditions.

Abstract
A method for a predicting golfer'"'"'s performance is disclosed herein. The method inputs the pre-impact swing properties of a golfer, a plurality of mass properties of a first golf club, and a plurality of mass properties of a first golf ball into a rigid body code. Ball launch parameters are generated from the rigid body. The ball launch parameters, a plurality of atmospheric conditions and lift and drag properties of the golf ball are inputted into a trajectory code. This trajectory code is used to predict the performance of a golf ball if struck by the golfer with the golf club under the atmospheric conditions. The method can then predict the performance of the golf ball if struck by the golfer with a different golf club. The method and system of the present invention predict the performance of the golf ball without the golfer actually striking the golf ball.
