Abstract: 1 550 nm photon Doppler velocimetry and terahertz-wave Doppler interferometric velocimetry were used in the initiating and flyer driven experiments to gain data on the temperature effect for the TATB/RDX based explosive. Explosive/window interfacial velocity, run distance to detonation and the velocity of flyer driven by the explosive were measured respectively at different temperature. Experiment results at temperature –45, 20, and 70 ℃ reveal that the run distance to detonation, the reaction zone time width and the detonation phase velocity decrease with temperature. In particular, the run distance to detonation and the reaction zone time width both decrease almost linearly, while the linear coefficient is found to be 0.015 mm/℃ and 0.165 ns/℃, respectively. With the increase of temperature, the detonation phase velocity of TATB/RDX based explosive decreases nonlinearly, which differs from TATB based IHEs, for which it decreases linearly. Four stages obviously exist during the motion of the flyer, i.e., spallation, pursuit, remerging and the united flyer. Divergent or grazing detonation driving condition can be resolved based on the analysis for the spallation duration in big plate driven experiment. The peak velocity and the velocity during spallation for the flyer vary with temperature in the same trend. The velocity at ambient temperature is the highest, hot one is the next and then the cold one. This may be related to the different reaction zone performance at different temperature. When the flyer united as a whole again, the final velocity under cold environment turns to be the highest one, the hot result almost equals to the ambient one, which may be related to the different detonation product performance at different temperature. The metal accelerating behavior at different temperature indicates that the reaction zone and the detonation product for TATB/RDX based explosive vary with temperature with the different path, which need more experiment data and numerical simulation for further investigation. -
