Abstract

This work present experimental results of PETN ignition and of numerical simulations of PETN, RDX, HMX, and TATB ignition by a copper oxide (CuO) film heated using a millisecond fiber laser YLS-150. It was established that the dynamic ignition threshold of organic explosive materials (EM) in a three-layer system (glass – CuO – EM) by a laser pulse has a minimum at the CuO film thickness of 12um. The density of the critical ignition energy of EM is increasing in the sequence of PETN, RDX, HMX, and TATB with PETN having the smallest and TATB having the highest density of the critical ignition energy.
