Abstract: |
Objective To obtain the reaction degree of munitions under sympathetic detonation, to provide technical support to the evaluation of munitions safety and sensitivity. Methods The sympathetic detonation test of a certain type of munition was carried out based on the STANAG 4396 of NATO. The overpressure, the distortion and damage of witness, the velocity of fractions were measured; additionally the expanding velocities of munitions case were obtained based on the Photonic Doppler Velocimetry - PDV). Results The flank witness face to the acceptor distorted more seriously than to the donor. The overpressure at 11 m and 14 m was 306 kPa and 177 kPa, which was almost the same as the effect of two munitions detonated. The case expanding velocities of donor and acceptor were also equivalent, which was about 3500 m/s. Conclusion In the given experiment conditions, the acceptor detonated. So the munition does not belong to insensitive munitions. In sympathetic detonation test, the expanding velocities of munitions case (both donor and acceptor) may be the key parameters to judge the reaction degree of munitions. |
