SUMMARY OF IMPACT TESTING FOR NASA PROJECT SUPER

Abstract

Hypervelocity impact tests were performed using Pegasus detector panels, simulated Saturn fuel tanks, and finite and semi-infinite targets. The impact velocity and crater parameters, where applicable, are given. It was determined that the output voltage of the Pegasus detector panels was not a function of projectile velocity nor of ambient pressure. The simulated Saturn fuel tanks showed evidence of burning after having been perforated by the projectile. The semi-infinite targets tested were 2024-T4, 6061-T6, and 7075-T6 Aluminum. Penetration data are presented for impact velocities from 11,000 to 30,300 fps and are used to determine values of target deformation stress. The correlation between the penetration data and an empirical relation using these stress values is approximately within + or - 2.5 percent. An empirical relationship to aid in crater volume prediction is presented. The results of the finite target work indicate that, to ensure that spall is not formed, the target thickness should be approximately 2.5 times the crater depth in a semi-infinite target.
