According to many badminton players, there are differences in impact feeling and flight trajectory between feather and synthetic shuttlecocks. Stiffness of the structural materials must affect impact feeling. Difference in flight trajectory is thought to be causally related to Reynolds number dependency of the aerodynamic drag and the unsteady forces due to added mass. In the present study, using vertical wind tunnel, number of revolution and dynamic drag acting on shuttlecocks in steady flight were measured for a range of Reynolds number 11,000 approximately less than Re approximately less than 15,000 at the angle of attack 0 deg. And unsteady drag and number of revolutions during accelerated motion were also measured by means of free-flight tests for a range of Reynolds number 10,000 approximately less than Re approximately less than 16,000. From the results of steady and unsteady aerodynamic force measurements, added mass around the shuttlecocks were estimated.
