Abstract

With the purpose of researching the defects' influence on detonation velocity of melting-cast explosive, the detonation velocities of RDX/TNT melting-cast explosives with different kind of defects in charge were studied using experimental method. It is found that the defects in different components lead to different influences on detonation velocity, and the defects in TNT decrease the detonation velocity to the great extent. So the defects removal in TNT should be emphasized to ensure high performance of explosive. By inference, the key factor is the size of defects is the key factor to weaken the performance of explosive. Considering the experimental results, the ω-Γ equation could be modified and the new equation would materialize the relationship between component density and detonation velocity.
