Since many years, SNPE is trying to get a better understanding of the mechanisms which govern the bullet impact reactivity of highly confined eastable plastic bonded high explosives. In a first part, the different research thrust lines and the principal results are presented. In a second part are presented some results of bullet impact tests performed with instrumented small scale warheads which can be open after test without hazard. These small scale warheads are filled with disks of explosive and inert material. The presence of this inert material, which has the same mechanical properties that the explosive, allows to reduce the level of reaction and then, it is possible to: measure the stresses induced by the impact, localize the ignition points, assess the amount of damage, determine the amount of explosive having recated.
