IMPACT TESTS WITH SINGLE OR MULTI IMPACTORS USING A GAS GUN TO REPRODUCE IEDS’ AND UNCOMMON THREAT

This paper deals with the ability to launch single impactor, sometimes with controlled angles, or synchronized multi-fragments using guns so as to reproduce Improvised Explosive Devices (IEDS) threats. This is done for a wide range of materials from aluminum and steel (light weight tactical wheel vehicle or fragments in detonation chamber [1]) to tungsten heavy alloys (rear face of heavy vehicle, hypervelocity events or hydrodynamic experiments [2][3]). Velocities spectrum is relatively large and englobes aeronautical subsonic regime (<300m/s), common ballistic regime (300-1400m/s) or warheads and hypervelocity regimes (>1400m/s).
