An Answer to the Question about the Energetic Performance of TKX‐50

Abstract

AbstractSome of the relevant detonation performance parameters of TKX‐50 were re‐determined. The enthalpy of formation was obtained from the measured heat of combustion to be ΔH°f (TKX‐50(s))=+213.4±1.2 kJ mol−1. The heat of detonation was measured to be 4650±50 kJ kg−1. The detonation velocity of a TKX‐50/wax mixture (97 : 3) at a density of 1.74 g cm−3 was found experimentally to be 9190 m s−1. Using the experimentally obtained enthalpy of formation for TKX‐50 of +213.4 kJ mol−1 and the experimentally determined solid‐state density at room temperature of 1.887 g cm−3 (TMD), the computed performance parameters for TKX‐50 at its theoretical maximum density at room temperature was calculated to be as follows: VoD=9642 m s−1, pC‐J=37.0 GPa and Qdet=4770 kJ kg−1.
