Influence of Cast Composite Thermobaric Explosive Compositions on Air Shock Wave Parameters
Danica Simić Milorad Popović Radoslav Sirovatka Uroš Anđelić
This paper describes the effects of compositions on the detonation properties and the parameters of the air shock wave front on a lightweight model of cast thermobaric explosives, TBE (400 g). Within this investigation, 14 thermobaric explosive compositions have been analyzed. Depending on the content of explosive, binding and oxidation components, as well as on the content of Mg / Al as a fuel, the basic parameters of the shock wave speed, maximum pressure (Put)max, overpressure (Δp) and TBE pressure impulse have been determined at different distances from the explosion center. The thermobaric effect examination was performed by the method of measuring overpressure in the shock wave front, using piezo-electric pressure transducers. The activation and the detonation of explosive charges as well as the expansion of detonation products were filmed by a Phantom V9.1 high speed camera. Key words: composite explosives, cast explosives, thermobaric explosives, air shock wave, pressure measurement, overpressure, pressure impulse, magnesium, aluminium
