A new method for evaluating the energy characteristics of C-H-N-O energetic compounds

From the law of conversation of energy, the release energy from the initiation to the Chapman-Jouguet point during the detonation of an energetic compound has been deduced as a function of initial density, detonation velocity, and detonation pressure. For C-H-N-O energetic compounds the relative release energy per unit volume (I_v) approaches the relative specific wall kinetic energy (E_cyl/E_HMX) at 19 mm wall displacement from the cylinder test with HMX as reference. A good linear relationship between I_v and E _cyl/E_HMX has been regressed, implying that E_cyl/E_HMX is also a function of initial density, detonation velocity, and detonation pressure. It has been concluded that I _v can reflect the driving force of detonation products of energetic compounds and is appropriate to be used for the evaluation of energy characteristics. The assessment of the energy for a series of synthesized and theoretically designed high-energy compounds reveals that the future of C-H-N-O energetic compounds is promising after CL-20 and ONC
