Using computational fluid dynamics (CFD) and data analysis, this study examines the relationship between drag force and trajectory parameters in badminton shuttlecock dynamics. Driven by the aim of making a valuable contribution to the design of badminton equipment, this study addresses critical research needs by scrutinising the intricate relationship between aerodynamics and trajectory. We examine shuttlecock aerodynamics using CFD simulations and drag coefficient calculations and apply them to trajectory computations. Important linkages emerge from the data analysis, showing that a higher shuttle angle of attack increases the height but reduces the range. We pinpoint the 40–70-g range of essential drag force that is linked to good serves. The results will provide useful information for improving badminton service performance and increasing gaming experience and sporting goods design.
