Based on aerodynamic principles and kinesiologic rules,the large scale wind tunnel simulation which can produce gentle breeze is designed.Through large-scale wind tunnel tests under different wind speed,the air force and flight path of patter ball is tested.Technical indicators,such as the weight,feather length,height and material of the ball is repeatedly modified and adjusted.And the wind proof patter ball which can enable the people to do exercises with it in gentle breeze.
