Type Of Shuttle For Badminton

Shuttle :

Shuttle

The shuttle may be made from natural and/ or synthetic materials. From whatever material the shuttle is made, the flight characteristics generally should be similar to those produced by a natural feathered shuttle with a cork base covered by a thin layer of leather. The shuttle shall have 16 feathers fixed in the base. The feathers shall be measured from the tip to the top of the base and each shuttle shall be of the same length. This length can be between 62mm and 70mm. The tips of the feathers shall lie on a circle with a diameter from 58mm to 68mm. The feathers shall be fastened firmly with thread or other suitable material.
The base shall be 25mm to 28mm in diameter and rounded on the bottom. The shuttle shall weight from 4.74 to 5.50 grams.
The skirt, or simulation of feathers in synthetic materials, replaces natural feathers. However, because of difference in the specific gravity and other properties of synthetic materials in comparison with feathers, a variation of up to 10 percent is acceptable.
Subject to there being no variation in the design, speed and flight of the shuttle, modifications in the above specifications may be made with the approval of the member association concerned. In places where atmospheric conditions due to either altitude or climate make the standard shuttle unsuitable. If special circumstances exist which make it otherwise necessary in the interest of the game.
To test a shuttle, use a full underhand stroke which makes contact with the shuttle over the back boundary line. The shuttle shall be hit at an upward angle and in a direction parallel to the side lines.
A shuttle of correct speed will land not less than 530mm and not more than 990mm short of the other back boundary line.
