Description

A shuttlecock used for badminton has an extremely complicated shape in comparison with other sport projectiles and quickly flips over after hitting by a racket. Although the flip of a shuttlecock is a fundamental behavior during badminton game, aerodynamic characteristics of the shuttlecock flip have scarcely been studied from engineering's point of view. Concerning the investigation of the shuttlecock flip, a computer simulation based on proper aerodynamic properties is a best tool. This paper describes a possibility of the flip simulation in which shuttlecock aerodynamic properties are acquired by using images of shuttlecock trajectory experiment captured by a high speed video camera without a wind tunnel experiment. Through the comparison between experimental and simulated results of shuttlecock trajectories, a fairly good agreement is obtained and the possibility of the flip simulation has been shown.
