FORMATION AND PROPAGATION OF SHOCK WAVES IN THE EARTHʼS ATMOSPHERE

Abstract

A new approach is proposed to estimate the amplitude of shock waves and compression waves in the atmosphere caused by explosive sources: industrial explosions, powerful explosions of concentrated charges, explosions of condensed chemical explosives and explosions of gas mixtures. As a result of generalization of the data of instrumental observations, the possibility of using M.A. Sadovskyʼs formulas to describe the mechanical effect of shock waves in the atmosphere for all the above sources is shown by taking into account the dependence of the scale coefficients of the law of energy similarity and the TNT equivalent of the explosion on the volumetric energy density in the source, which makes M.A. Sadovskyʼs formula universal for calculating the parameters of the mechanical action of explosive charge explosions with any state of matter, different properties and energy characteristics. The data obtained can be used to prevent the negative consequences of the use of explosive technologies in the national economy and during experimental explosions of explosives.
