- Abstract
The projectile of a 2 staged light gas gun has mostly spherical shapes. On the other hand, in the shaped charge system more accelerable to a high speed, it is checked also from the experiment of authors that the configuration of a jet is close to a hollow cylinder. So, in order to judge the test result using a shaped charge more exactly, the effect which the configuration of projectile has on breakage needs to be evaluated. Then, using a 2 staged-light gas gun which can change the configuration of projectile comparatively easily, the configuration similar to a shaped charge system was injected, and the check evaluated about the effect which a projectile configuration has on breakage was done. As a result, when the projectile from which only a configuration differs with the same mass at the same velocity to collide with a thick board, it turned out that there is no big difference in a breakage configuration. On the other hand, in the collision to a multiplex bumper configuration, it turned out that the effect which a projectile configuration has to a breakage configuration is great. This investigation shows the above check outline and a result. Moreover, the result evaluated about the validity of the method of a collision test to the bumper configuration using a shaped charge is shown.
