See attached notebook for details. A shuttlecock (previously called Shuttlecork) (also called a bird or birdie) is a high-drag projectile used in the sport of badminton. It has an open conical shape: the cone is formed from 16 or so overlapping feathers, usually goose or duck, embedded into a rounded cork base. The cork is covered with thin leather. The shuttlecock’s shape makes it extremely aerodynamically stable. Regardless of initial orientation, it will turn to fly cork first, and remain in the cork-first orientation.
The name shuttlecock is frequently shortened to shuttle. The “shuttle” part of the name was probably derived from its back-and-forth motion during the game, resembling the shuttle of a loom; the “cock” part of the name was probably derived from the resemblance of the feathers to those on a cockerel.
Another gem, thank you for sharing! Amazing how simple models couple to produce full dynamics - the shuttlecocks flip model and trajectory model - I hope I understood final equations correctly. But is the flip model is mathematically analogous to pendulum with friction?
If you lower the initial velocity V (say V=V/10), then you can see the typical trajectory of a spinning net shot. I did not try to find good mapping between parameters’ initial values and for all the shots described in the paper… but maybe Mariusz had not planned anything for the summer?
I’ve never played in Badminton.What is spinnig net shot!. I searched a bit and after Googling and here is the resulting simulation.
I hope I understand what is it.
And since I’m having fun an I’m already asking too much, there’s no limit anymore: the incoming shot would typically start from a higher altitude, say z[0] = 2, and would stabilize much farther from the net.
