摘要

Thermobaric charges with four different liquid fuels and several powdered fuels were prepared and fired and their TNT-equivalencies in the open field were determined. The results show the shock wave component of ther-mobaric explosion originates mostly from anaerobic processes. The fuel component was deemed critical for the generation of a thermobaric explosion. Only IPN demonstrated advantageous properties and a reliable ignition of the fuel and metal powder components in all tested proportions. IPN was also the only fuel able to create effective, aerobic explosions even with excessive amounts of metal powder producing enormous overpressure pulses. The powdered fuel was deemed critical for the ignition delay in the aerobic stage, activated aluminium showing most promising properties followed by elektron, phosporus and boron. Metal combustion rate is a critical parameter in generating high pressure levels in the aerobic stage.
