摘要

The effects of copper micro-particles on the detonation characteristics of RDX powder were investigated in a horizontal shock tube with internal dimensions of 100 mm diameter and 4 m length using an instantaneous spectrum detection apparatus. The emergence time and emission spectral intensity of the main products such as NO2, H, C-2, O, CO, CH2O, CO2 and H2O were observed by a TDS5054 oscilloscope. With or without the addition of copper micro-particles into RDX, NO2 appears first in every experiment, which is in agreement with theoretical results. However, the addition of copper micro-particles to RDX can shorten the emergence time by 7-18%; it can also increase the peak blast pressure by about 133%. In addition, O-2, H2O and CH2O in various quantities were introduced into this experiment, respectively, which indicate that O-2 can obviously affect the results that may shorten the emergence time of NO2 by 31% and increase the peak blast pressure by 167%.
