ABSTRACT:
This invention relates to a new model plastic shuttlecock which composed of a round tail skirt without undulation and a mid-skirt zone with some reinforcing circles and stems of pyramidal section, which offers appropriate strength of its tail skirt. And there are two rows of air resistant surfaces which are extended from the end of the tail skirt towards the mid-skirt zone and the inner side of the feather wings. The air exhaust surfaces have many larger net shaped air stream outlets to make the shuttlecock rotate and balance the air pressure difference between the inner and outer sides of the feather wings increasing the accuracy and stability of stroke and flight of the shuttlecock and also preventing its swinging to and fro during flight.
