Now, in order to elucidate phenomena of high velocity, high velocity launching equipment, such as single stage gas gun, powder gun, and two stage gas guns are used. Generally, powder gun and two stage gas guns can launch a projectile high mass compared with a single stage gas gun. But, the working hours for cleaning the inside of a launch tube are required after launching a projectile, and since gunpowder is used, the deterioration of equipment is large compared with a single stage gas gun. On the other hand, a single stage gas gun can prepare launching projectile in comparatively short time. Moreover, there is an advantage that equipment degradation is small. In this study, the single stage gas gun which can be launched to a portable type and all the directions is developed. And the experimental result which launched various projectiles using the single stage gas gun is reported.
