Characteristics of thermobaric explosives and their advances

The detonation of thermobaric explosives involves ignition, detonation, propagation and reflection of shock wave, multi-phase turbulence, and multi-mode chemical reaction. It is a coupling process of multi-scale, multi-material, multi-factor, and multi-physical field. A deep understanding of the detonation mechanism of thermobaric explosion and effective control and utilization of the explosion are critical to the innovation and development of thermobaric weapons. It can guide the design, development and applications of high-power thermobaric explosives and weapons. Firstly, this paper describes the origin of thermobaric explosives and the basic principle of thermobaric explosion, and discusses the concept and connotation of thermobaric explosives. Secondly, the characteristics of thermobaric explosives from the aspects of explosive kinds, energy release characteristics, energy composition, blast reaction mechanism, blast effect enhancement mechanism and killing mechanism are elaborated. And then the evaluation method of explosion power of thermobaric explosives in confined space and the state of art of thermobaric explosives were summarized. Finally, we give some relevant suggestions that wcould provide guidance for the design of high power thermobaric explosive, the development of thermobaric bombs and damage assessment.
