Experimental Research on the Effect of Aluminum Additive on the Electromagnetic Radiation in Detonation Process

摘要

Explosions of explosives can produce electromagnetic radiation signals. Based on the theory of the explosion of electromagnetic radiation, the effects of metal additives on the electromagnetic radiation produced by explosive detonation should be researched. In this paper, the electromagnetic radiation signal characteristic produced by the passivation RDX of metal additives explosion were studied by experimental. The rod-shaped antenna measurement system was used to measure the electromagnetic radiation signals generated by the different percentages of aluminum-containing passivation RDX and pure passivation RDX. The results show that the intensity of the electromagnetic radiation signal produced by the explosion is obviously increased by mixing aluminum. In the case of the same explosive mass, the signal intensity of the electromagnetic radiation generated by the explosion increases with the aluminum mass percentage is increased. When the content of aluminum is the same, with the increase of the mass of explosives, the intensity of the electromagnetic radiation signal generated by explosion also increases. The main component of the electromagnetic radiation signal frequency generated by explosives is less than 1MHz, the electromagnetic spectrum generated by explosives with the same composition is consistent.
