Calculation of TNT Air-Blast Equivalencies for Surface Bursts

reportActive / Technical Report | Accession Number: AD0775422 | Open PDF

Abstract:

TNT air-blast standards for hemispherical explosive charges scaled positive unit impulse and peak pressure vs scaled distance are presented in graphical and tabular forms. Equations for positive unit impulse and peak pressure TNT equivalencies are derived, permitting rapid manual calculation. The equivalencies relate the weight ratio of TNT to the sample material in terms of their relative explosive airblast. The calculation of TNT equivalencies will facilitate and expedite the efficient, reliable establishment of intraline distances in production facilities and loading plants. A FORTRAN Extended computer program with complete documentation and sample input and output is included in this study.
