【Abstract】 Spin detonation of cast charges TNT DINA and DNT PETN was studied. Detonation parameters of the systems are capable of propagation in the form of spin pulsating detonation at low frequencies. All such systems appear to have a detonation velocity D J of 7.3 ～ 7.4 km/s and practically the same explosion heat Q v=( 5.40 ± 0.01 ) MJ/kg. The calculated velocity and pressure ( P J) of detonation vs. content of sensitizer were analyzed and shock temperatures were calculated by means of the SW computer code. A pressure ( P 3) and a temperature ( T 3) in the peripheral zone where damping and reinitiation of detonation take place were estimated. The P J values for TNT RDX mixtures are higher than those for TNT DINA blends with the same content of sensitizer RDX or DINA. Accordingly the temperature T 3 for the former system is 60～100 K higher than that for the latter. Experimental data are in good agreement with calculated results.更多还原
