Abstract EN
A new analytic model of aluminized explosive products based on the method of characteristics for planar isentropic flow is proposed herein.
The contribution of Al oxidation in the explosion products is investigated analytically.
The flow behind the detonation front cannot be treated as isentropic due to the Al oxidation in the products.
To solve the nonisentropic flow field of aluminized explosives products analytically, the assumption of local isentropic process is proposed.
Based on this assumption, the flow field behind the detonation front of aluminized explosive is a function of only the reacted aluminum mass fraction in each time range.
The metal plate test was conducted with the metal plate driven by RDX/Al/wax (76/20/4) and RDX/LiF/wax (76/20/4).
The reacted aluminum mass can be obtained indirectly from the experiment results.
The reacted aluminum mass was then applied to the analytic model, and the velocity of metal plate driven by RDX/Al/wax (76/20/4) and RDX/LiF/wax (76/20/4) was calculated.
The final velocity of the metal plate driven by RDX/Al/wax was 7.8% higher than that driven by RDX/LiF/wax.
