UNIFIED INVESTIGATION OF SECONDARY BEHIND ARMOR EFFECTS
The use of modern weight-saving materials in military vehicles and the increasing variety of threats demand for a more detailed understanding of the phenomena possibly occurring upon a perforation of the vehicle protection. One important issue is the increase of pressure and temperature inside a compartment that is perforated by a projectile. For a systematic scientific investigation of the underlying phenomena, we used a small vessel equipped with pressure and temperature sensors as a model for a closed compartment. A kinetic energy (KE) penetrator, a shaped charge (SC) and an explosively formed penetrator (EFP) charge were scaled such that a wide spectrum of projectiles could be investigated with one unified experimental method. Thereby, it was possible to perform a direct comparison of the effects resulting for different target wall materials as well as for different threats. Besides the quantitative pressure and temperature measurements inside the vessel, the basic phenomenology of the underlying physics has been investigated in singleplate-perforation experiments with the help of highspeed video cameras.
