Performance of TKX-50 and its formulations in comparison with RDX, HMX and some other HE

Abstract. A large complex of thermochemical, thermodynamic, gas dynamic and solid dynamic calculations was made to determine the performance of the TKX-50 explosive and a number of its formulations and compare this with the same of RDX, HMX, and some other HE. The Explo5 and Ansys Autodyn programs were used mainly for doing calculations. First of all, the detonation products properties, ranges of the most significant values of the detonation characteristics of all HE and the equations of state of their detonation products in the form of JWL were determined in thermochemical and thermodynamic calculations. The calculations for TKX-50 were made for the most plausible experimental values of the enthalpy of formation and for two modifications of the BKW equation of state. For the considered TKX-50 formulations with different inert and energetic binders, detonation characteristics were determined for a binder content of up to 10% and a porosity of up to 5%. An analysis of the influence of all the specified factors on the detonation characteristics of the TKX-50 explosive was performed. Similar calculations were made for RDX, HMX, their formulations and some other explosives and such results were compared with the results obtained for TKX-50. Then some regularities of the explosive impact of the considered HH on barriers made of various metals with different properties, in particular, in the density range from light beryllium to heavy uranium were determined in gas dynamic and solid dynamic calculations. The calculations were performed for conditions of surface loading of barriers by an incident detonation wave, for conditions of internal loading of thick barriers by a passing shock wave, and for conditions of acceleration of thin plates by an explosion. The results obtained in the work can be used in the design of explosive devices containing TKX-50 as the energy source.
