Two-stage model of explosive propulsion of metal cylinder
Apstrakt
The paper considers acceleration of cylindrical metal liner by expanding detonation products. A new analytical model of liner motion is developed for the cases of axisymmetric (head-on) and grazing (side-on) detonation of the explosive charge. Suggested model relies on the two-stage regime of cylinder motion: (i) the first stage is the consequence of detonation wave-metallic liner interaction; as the result initial velocity is imparted to the liner, (ii) the second stage is gas-dynamic push of the liner governed by detonation product expansion, similarly to the Gurney
approach. Results of the analytical model are validated by comparison with available experimental data.
