スポーツウエルネス吹矢に関する実験とシミュレーション

抄録

In ancient times, blowgun was used as a simple ranged weapon to hunt small animals. Today it is mainly used for sport wellness in Japan and is called Fukiya. The underlying principles of blowgun, especially the dynamic behaviours of the dart and the airflow in a blowpipe have not been studied sufficiently. In order to assist the design of new sport wellness blowguns, in particular, to design a dart which can travel horizontally in the blowpipe with small air resistance and can fly along a desired direction and distance, experiment and computer simulation for sport wellness blowgun were carried out. The experimental apparatus consists of the blowing system and high-speed video camera system. The blowing system is composed of a dart, a blowpipe, a mini digital angle meter and a compressor. The high-speed video camera system is composed of a video camera, a control unit, a synchronizing unit, an analog-digital converter, and a personal computer.

A moving particle simulation (MPS) software called Particleworks was used in the computer simulation.
