Metal/Oxidizer energetic materials are mainly used as propellants in aerospace area because they can release high energy in a few micro-seconds in a closed vessel. The energy release performance of the energetic material plays an important role in the rocket motor design. Among materials, ZrKClO4, TiH2KClO4, BKNO3 have been widely used for decades. ZrKClO4 has advantages of simple ignition characteristics and high energy density but has large performance deviation. TiH2KClO4 and BKNO3 have relatively low energy but have small performance deviation because of its stability. These propellants are tried to use in the mixed form of ZrKClO4/TiH2KClO4 and ZrKClO4/BKNO3 to increase the stability of energy release. However, despite the importance of estimating performance, the existing models are based on empirical equation. In this study, we suggest the theoretical model to estimate the energy release performance of mixed energetic materials. The model is compared with the experimental results for verification. |
