Equation of state of the detonation products of RDX

Progress and performance of energetic materials: open dataset, tool, and implications for synthesis

“…Pepekin, Kuznetsov, and Lebedev (PKL) 88 proposed another method for high-density charges of CHNOF compounds using the detonation adiabat, equation of state, 89 and the experimental data for RDX. The authors introduced several simplifications and finally derived the following equation: D 2 = 8.0[ Q 1 + ( n eff /0.0349) 3 ρ 2 ],where Q 1 = Q cal /4.184/1000 + 0.74 n eff /0.0349.…”

Equation of state of HE detonation products

“…A comparison of our calculated results with experimental data of Ref. [8][9][10][11][12][13][14][15] for HMX and RDX is shown in Fig. 5.…”

“…Experimental data for HMX were borrowed from Ref. [9], and for RDX, from Russian publications [10][11][12][13][14][15]. Our detonation calculations for RDX were performed with an equation of state of RDX detonation products defined in the form of two regions with the following parameters: ρ o = 1.05 g/cm 3 ; Bo = 9.7 GPa (region I), ρ o = 1.255 g/cm 3 ; Bo = 18.3 GPa (region II) and caloric value of explosive Q = 3.4 kJ/g.…”

“…Paper [18], with reference to [10][11][12][13][14][15], presents Jouget pressure values measured in RDX of different initial densities. Figures 6-18 show a comparison of these data with our calculated values.…”

“…[8,9], and squares are for RDX from Refs. [10][11][12][13][14][15]. The upper calculated curve is for RDX, and the lower one is for HMX.…”
