Reactive flow measurements and calculations for ZRH sub 2 -based composite explosives
Cylinder test, Fabry-Perot laser interferometric and detonation velocity-charge diameter experiments were done to determine the detonation reaction zone structures and reaction product equations of state of a family of HMX/AP/ZrH{sub 2}/estane explosives. This experimental data base is used to develop ignition and growth reactive flow models of the detonations waves in these composite explosives. The experiments and calculations clearly demonstrate the Zeldovich-von Neumann-Doering (ZND) structure of the detonation reaction zones which are several millimeters long. The inferred reaction rates imply that the HMX in these formulations reacts first at rates comparable to those measured in other HMX-based explosives and propellants. The remaining components of these explosives then decompose at much slower rates. However, this decomposition is rapid enough to contribute to the propagation of the detonation wave and to the total energy delivered in metal acceleration applications. 22 refs., 9 figs.
