Abstract
As you know, badminton is a well-known sport that young and old can play. The reason why everyone can enjoy is in strong deceleration of the shuttlecock, however, its aerodynamic characteristics have not been elucidated well. In the present work, using a low speed wind tunnel, effects of the flow passing through the slot located at leg part of the feather on the aerodynamic characteristics are demonstrated. Aerodynamic force and moment acting on the shuttlecock and flow field structure in the shuttlecock are measured in angle of attack rage from -10 to +10 degrees. The result shows: 1) The flow over the base surface separate at the shoulder of the base part, and formed a short bubble above the filled slot, and 2) As for normal configuration, dead water region is formed just behind the base part by the through flow from the slot#1. Pressure of this region is very low, and lead to pressure-drag increase.
