Abstract

New official volleyball made by Mikasa Co. Ltd. was used in the volleyball game of the Beijing Olympics. However, the report for aerodynamic characteristics of the new official volleyball has not been done until now. In this report, comparison of aerodynamic characteristic of official volleyball used until now and new official volleyball adopted in the Beijing Olympics (2008) is carried out. From these results, we clarify an aerodynamic characteristics for rotation and unrotation of new official volleyball and old official volleyball.
