People often use the expression “striking the ball on the centroid” in baseball and golf.
It makes you feel sure that the swing energy is completely transferred to the ball.
This expression is often used in badminton, but the mechanism has not been clarified so far.
If only we could make a racket that the players could feel of striking the shuttlecock on the centroid in badminton….
It was necessary to study such a feeling to proactively achieve centroid-striking shot rather than an accidental centroid-striking shot.
Badminton is not a racket game to hit a spherical ball, but a special game to hit a shuttlecock that is complicatedly composed of a cork part and a feather part.
Furthermore, this is a sport where the difference between the initial speed and the final speed is great, and the shuttlecock’s flight trajectory after impact is extremely complicated.
GOSEN took shots of this complicated mechanism with an ultra-high-speed camera and analyzed it.
GOSEN proceeded with the development of a racket equipped with the factors necessary to fulfill the requirements.
The racket created from the new development concept was named GRAVITAS (meaning gravity in classical Latin) from the phenomenon of the shuttlecock crushed at the moment when the racket hit it on the centroid.
The moment the racket hits the shuttlecock on the centroid, the racket crushes the shuttlecock and produces greater and higher delivery speed.
The feather part bounces, and the shuttle speed becomes the fastest.
Sudden deceleration from the initial velocity to 75%. While the entire shuttle is deflated, the feather part repeatedly expands and contracts.
The cork part faces upward and maintains the speed while maintaining a non-rotating state.
The cork begins to point downwards, and the entire shuttle shape gradually begins to stabilize.
The shuttle shape is completely restored, and it begins to rotate counterclockwise from the direction of hitting and then decelerates again at a constant speed.
