The four main factors that affect the stability of badminton movement, follow the badminton manufacturers to understand.
1. Uniform vane weight;
2. Consistency of pinna arches;
3. The vanes are arranged at the same angle;
4. The weight ratio of the feather to the ball.
I wonder if golfers remember an artificial badminton called Carbon Tone. To be infinitely close to the natural sphere, this artificial ball uses 16 wool pieces, and maybe no more wool pieces, the carbon sound material “feathers” are all synthetic. To find out the relevant data at that time, you can look at the comparison data:
Natural heavy ball 5.060g.
Artificial spherical: 5.134g.
The weight of the artificial ball is slightly larger by 0.07g.
Contrast value of natural sphere diameter: 67.53 mm.
Artificial sphere: 6.52 mm.
The artificial sphere is slightly smaller by 1 mm.
Natural ball hair contrast: 63.54mm.
Artificial sphere: 61.50 mm.
The artificial sphere is slightly shorter by 2 mm.
Professionally, there is still a certain gap between carbon-tone badminton and traditional badminton. Professional players can often feel that their hitting feel is slightly different from traditional badminton. Specifically, comparing the above four main factors, the first three notes are all done perfectly, while the fourth is the weight ratio of the shuttlecock to the ball, which has not been done yet. The hardness of the charcoal hair blade is not high enough, and it is difficult to maintain a fixed angle, which affects the stability of the flight.
