“…There is one feature of the nitromethane detonation that we have ignored. Numerous experimenters have reported results which suggest that there is a dark wave structure superimposed on the gross features of the detonation front even for large-diameter charges (Davis 1965;Dremin & Savrov 1966). However, measurements of the shock…”

An analytical steady-state theory of the detonation ‘diameter effect’ is presented. This theory, which includes the off-axis flow, is a generalization of the Wood-Kirkwood analysis. When the state dependence of the reaction rate is stronger than that of the product of the sound speed squared and the flow divergence, detonation failure can occur. The leading term in the extrapolation of the detonation velocity to infinite charge size is quadratic in the inverse charge size and not linear as popularly believed. When calibrated to the detonation velocity vs. charge-size data, the theory reproduces the limited amount of experimental shock loci to a high degree of accuracy.

“…The electromagnetic particle velocity measurement method for non-conducting or weakly conducting dense media was introduced in the Russian literature by Zaitsev et al [35]. The method has since been widely exploited by Dremin and other Russian workers [36][37][38][39][40] for measuring particle velocity in detonations and in media shocked by detonation wave impact.…”

This paper documents the design and construction of a 50 mm bore laboratory gas gun capable of velocities up to 1500 m s −1 . The facility is designed using performance calculations using the analytical interior ballistics model of Pidduck and Kent (Seigel 1965 National Technical Information Service, AD475 660). The gun is constructed for two opposing classes of experiment. One of these geometries is that of plate impact, in which the loading is in one-dimensional strain, accomplished by impacting plane impactors onto targets aligned to micron tolerances, precisely normal to the impact axis. A second is multidimensional loading including the impact and recovery of specimens after soft recovery in catching systems. The system is capable of containing reactive targets when design must allow complete detonation of the target (up to 250 g). This has been accomplished and the system approved for use by the appropriate authorities. An example of the development of a multi-element particle and shock velocity measurement system is included to illustrate the new measurement systems in place.
