The correct answer is 16 feathers.
A standard, tournament-grade badminton shuttlecock is constructed using exactly 16 feathers fixed into a cork base.
Anatomy and Aerodynamics of a Shuttlecock:
- Symmetry and Balance: The Badminton World Federation (BWF) strictly regulates the design of competitive shuttlecocks. Exactly 16 feathers are used to guarantee perfect aerodynamic symmetry, ensuring the shuttlecock spins smoothly through the air and stabilizes rapidly after a high-impact smash.
- Material Sources: Premium tournament shuttlecocks are made using the left-wing feathers of a goose or a duck. Left-wing feathers are specifically selected because they all curve in the exact same direction, causing the shuttlecock to spin clockwise during flight.
- The Base: The feathers are inserted into a premium cork base wrapped in thin leather. They are then securely bound together with thread and glue to maintain their cone shape.
Comparison of the Options:
- 12 feathers: Incorrect. A shuttlecock with only 12 feathers would have large gaps, reducing air resistance and causing it to fly too fast and destabilize.
- 15 feathers: Incorrect. An odd number or an asymmetrical arrangement of feathers would ruin the axial spin, causing the shuttlecock to wobble in the air.
- 10 feathers: Incorrect. This is far too few feathers to create the necessary drag required for a predictable flight path.
- 16 feathers: The correct answer; this precise number balances weight, drag, structural durability, and optimal spinning speed.
