An advent of a synthetic shuttlecock contributes greatly to a badminton game because of a cheap and stable supply of shuttlecock. Since the synthetic shuttlecock must be produced as same as a natural feather shuttlecock, the difference between synthetic and feather shuttlecocks must be checked. A computer simulation based on proper aerodynamic properties is a best tool to investigate this difference. This paper describes a measuring method of shuttlecock aerodynamic properties using images of shuttlecock trajectory experiment captured by a high speed video camera without a wind tunnel experiment. Through the coincidence between experimental and simulated trajectory results, the drag, lift and pitching moment coefficients and damping factor were identified with a fair accuracy. The obtained data are verified through the comparison between experimental and simulated results of other trajectory experiment. The difference of predicted trajectories between feather and synthetic shuttlecocks were discussed for four common badminton shots.
