To perform a non-intrusive measurement on a pyrotechnic setup, we usually use radiography. But, the X-ray generator and the detectors of the radiographic chain must be protected against the blast and. We carried out an experimental campaign to test the performances of various shielding. Representative cylindrical projectiles with various masses (from 20g to 40g) and aspect ratios (length to diameter ratio from 0.1 to 1) were launched with a gas gun at different initial velocities (from 1500m/s up to 2000m/s). Multiple shield configurations, based on assemblies of steel, aluminum and B4C plates were tested. The experimental results were combined with numerical studies to demonstrate the capabilities of the shield to stop fragments. [ABSTRACT FROM AUTHOR] |
