摘要

Explosion reaction process of solid Fuel Air Explosive (FAE) is complex owing to multi-phase explosion. It is difficult to value its thermal damage effects directly. In this paper an improved single-wavelength pyrometer is used for measuring temperature of the center of solid FAE, and the temperature-time curves of explosion products were obtained. The measurement results are compared with equal mass of TNT. The explosion radiant energy received by the pyrometer's detector is worked out by Planck's Law when solid FAE and TNT are detonated. It makes the evaluation of effects of thermal damage of TNT and solid FAE with different recipes come true. The experimental data show that solid FAE with various recipes has different thermal damage performance, and the solid FAE's thermal damage effects are greater than TNT of equal mass. The phenomenon of high speed photographs agrees well with the valuation result of solid FAE's thermal damage effects.
