Measurement of Momentum to Move with Hypervelocity Impacts of Projectile

Abstract

In this study, the momentum of the target when collided with a projectile at hypervelocity was measured. Pendulum targets were used in the experiments. The momentums of the target were calculated based on the maximum swing angle of the pendulum. The target material is comparable to aluminum alloy which was used for the rocket body. It is confirmed that, as the impact velocity increases, the ratio of momentum of the projectile before impact and the momentum of the target after impact changes. Furthermore, as the thickness of the target changes, the ratio of momentum of the projectile before impact and the momentum of the target after impact changes.
