TATB、TCTNB和TCDNB的爆轰性能

Detonation Performance of TATB、TCTNB and TCDNB

用电探针和锰铜压力计分别测定了Ф20mmTATB、TCTNB/Wax(97%/3%)以及TCDNB/Wax(97%/3%)3种药柱的爆速和爆压,同时用VLWR爆轰程序计算其爆轰参数和C-J产物的平衡组成。实测结果表明,TATB爆速为7.452mm·μs-1,爆压为24.40GPa;TCTNB97%和Wax3%配方的爆速为6.890mm·μs-1,爆压为20.28GPa;TCDNB97%和Wax3%配方的爆速为5.973mm·μs-1,爆压为15.30GPa。理论计算值和实验值比较接近,获得了较好的结果。

The detonation velocity and pressure of Ф20mm cylinder TATB、TCTNB/Wax (97%/3%) and TCDNB/Wax (97%/3%) have been measured by ionization probes and manganin gauge, and their detonation parameters and the equilibrium composition of detonation products at C-J state have been computed by means of the VLWR code. The testing results show that the detonation velocity and pressure are 7.452 mm·μs^(-1) and 24.40 GPa for TATB, (6.890) mm·μs^(-1) and 20.28 GPa for TCTNB and 5.973 mm·μs^(-1) and 15.30 GPa for TCDNB respectively. The calculated results were close to experimental values,showing that the calculated results are satisfactory.
