Determination of Main Thermodynamic Parameters of Thermobaric Ammunition Explosion

Abstract

A large number of weapon systems have been emerged over the last few decades. Most of these parts create an explosive for poles using fragmentation or cumulative jet. Until recently, some combat units identified the explosion as a major factor. But new technologies have made it possible to develop warheads that improve the characteristics of the explosion and use it as one of the main methods of impacting the target, i.e thermobaric warheads.
 Ammunition equipped with mixed (multicomponent) thermobaric explosives has many advantages over ammunition equipped with conventional explosives. They are more economical (cheaper to manufacture), safer to use and have adjustable thermodynamic characteristics, as well as the composition of products, which allows you to choose the optimal filling of thermobaric ammunition to perform specific tasks.
 The article proposes calculations and methods for determining the main thermodynamic parameters of thermobaric ammunition explosion, namely: heat of explosion, volume of gaseous products, temperature and radius of high temperature area, excess pressure in front of the shock wave and its speed taking into account the physical characteristics of thermobaric explosive.
 The peculiarity of the above calculations and methods is to take into account the physical characteristics of the explosion of the explosive mixture.
