SOME EXPERIMENTS ON HYPERVELOCITY IMPACT

Abstract

Crater dimensions have been obtained in various metal targets when attacked by 1/4 in. diameter spheres with velocities up to 10,000 ft/sec. The depth of penetration in semi-infinite targets attacked at normal incidence has been correlated with an empirical formula which is in agreement with existing work. When the semi-infinite targets were attacked at incidence the depth of penetration was found to be proportional to the sine of the angle of incidence. When thin targets were attacked at incidence the crater dimensions were similar to those obtained for semi-infinite targets inclined at the same angle provided the thin targets were not penetrated. An empirical relationship is given for a minimum thickness of target for non-penetration as a function of the impact velocity, the properties of the target and projectile and the angle of incidence.
