THE DETERMINATION OF CHARACTERISTICS OF TEMPORAL PULSATING CAVITY WITH GUNSHOTS FIRED FROM FORT-12 GUN

Abstract

The article presents the analysis of morphological peculiarities of temporal pulsating cavity under the experiment conditions using ballistic gel. In the course of the experiment there was used Fort-12 gun and standard ammunition of 9*18 mm caliber. A 250 Bloom ballistic gel (recommended by the leading researchers) was chosen as a simulator. The preparation of gel blocks was conducted using a classical methods suggested by Fackler and Malinowski, the concentration is 10 %, cooled down to the temperature of 4 °C (the exposition time is 48 hours). The visualization of a wound tract and cracks in gel left by the gunshot projectile and liquidation of the temporary pulsating cavity was conducted with the use of a contrasting water-soluble dye. After that the blocks were photographed and cut across the wound tract into plates of 1 cm width. Each section was scanned individually with the use of a flatbed scanner. In order to evaluate the damaging effect of the wounding projectile there are used standard calculation methods: Fackler’s wound profile (WP), the total crack length method (TCL), the polygonprocedure (PP).
