| Abstract: | Addressing the critical issue of Flame Over in fuel air explosive (FAE) warheads, which severely affects their safety and reliability, this study proposes the use of Inert Fillers as an effective means of suppression. The study’s innovation is the selection and application of three distinct types of Inert Fillers: nitrogen, carbon dioxide, and high efficiency fire extinguishing agents. By observing the maximum temperature of the Explosive Fireball and the cooling rate during the test process, the study evaluates the ability of these Inert Fillers to mitigate the Flame Over phenomenon. The findings reveal that Inert Fillers can suppress Flame Over by lowering the maximum surface temperature of the Explosive Fireball and increasing the cooling rate, with the high efficiency fire extinguishing agents showing a more pronounced inhibitory effect. In summary, these Inert Fillers have been proven to significantly reduce the maximum temperature of the Explosive Fireball, with the high efficiency fire extinguishing agents being the most effective in temperature reduction and cooling rate acceleration, thus providing essential support for the Safety Design of FAE warheads. |
