ABSTRACT
This paper introduces six-term models that characterize the aerodynamic lift and drag behavior of a broad range golf balls during a driver trajectory. These models are based on the measurements made of a wide variety of golf balls using the USGA’s Indoor Test Range (ITR). They are useful in that, with a few parameters, they accurately describe the nonlinear nature of golf ball lift and drag at the low speeds encountered at the end of a driver trajectory, as well as the effects of different spin rates. The result is accurate simulation of golf ball trajectories.
