Abstract

Abstract

In this work we used the laser velocity interferometry for measuring particle velocities and the wedge-shaped test explosive to study the structure of the chemical reaction zone of JBO-9021, a new insensitive high explosive (80 weight% TATB explosive, 15 weight% HMX explosive, 5 weight% binder). We conducted an experiment to achieve the in-situ particle velocity histories of a thin aluminium film between the test explosive and the LiF window that were introduced to obtain the particle velocities at different positions in the wedge-shaped test explosive after detonation. The CJ point of the particle velocity histories for JBO-9021 were derived from a second time derivative of the velocity history of particles from which we successfully obtained the chemical reaction structure, including the chemical reaction duration and the chemical reaction zone length. The results show that the chemical reaction duration of JBO-9021 is (238±13) ns and the chemical reaction zone length of JBO-9021 is about (1.52±0.09) mm. Additionally, they also show that the CJ point obtained from a second time derivative of the particle velocity histories is effective.
