Detonation velocity (VOD) is one of the most important parameters describing the detonation process of a particular explosive. This article summarizes some peculiarities that we have come across when building and testing our new passive optical VOD meter – OPTIMEX. The advantages of using multiple probes with independent signal recording is discussed. The practical issues related to an explosive’s translucency are solved. Finally, a new method for detonation velocity data evaluation is proposed and demonstrated.

OPTIMEX: Measurement of Detonation Front Curvature with a Passive Fiber Optical System

The ability of a newly developed independent passive optical system OPTIMEX to measure the detonation front curvature is demonstrated on charges of pressed explosive A-IX-1 (RDX/ceresin-stearin mixture with 95/5 wt.%). The charges, with length to diameter ratios of from one to four, were prepared from cylinders with diameters of 21 mm, 30 mm, 40 mm and 50 mm pressed to a density of 1.66 g/cm3. Such charges detonate with a velocity of 8220 m/s. The detonation curvature was obtained using 8 optical fibers and the results were compared with photographs acquired by an ultra-high speed framing camera UHSi 12/24.
