Abstract

As the safety of propellant has been paid more and more attention, the experiment of explosive-driven flyer impacting initiation propellant was simulated by nonlinear finite element software Autodyn17.0. The results show that the critical initiation pressure of the high energy propellant is about 2.95 GPa, the detonation wave growth distance is about 20-25 mm, and the highest pressure is 48.40 GPa.
