Abstract

Typically, soccer balls are constructed with 32 pentagonal and hexagonal panels. More recently Teamgeist and Jabulani balls have 14 and 8 panels, respectively, with dramatically different panel shapes and designs from conventional balls. The latest model called Beau Jeu, made with 6 panels, has been adopted by many soccer leagues. However, there are few studies on the aerodynamic characteristics of these balls. This study examined the trajectory and aerodynamic characteristics of soccer balls constructed with different numbers and shapes of panels. Results of wind tunnel tests indicated that the aerodynamic forces varied significantly according to the surface forms. The results showed that the ball trajectory changes according to surface form, suggesting that surface form has significant effects on the flight of the balls.
