The DNA Nuclear Blast Standard (1 KT)

Abstract

A set of subroutines has been developed which provide complete definition of the blast environment resulting from the free air detonation of a one kiloton device in a sea-level atmosphere. The subroutines provide the pressure, density, and velocity as function of space and time (from 1 ms to several minutes). The analytic fits are compared with results of hydrodynamic calculations and with experimental data. Blast parameters are as a function of radius at a given time. By successive calls to the routines, time histories of the various parameters may be generated. A complete set of scaling routines is included to permit definition of blast waves resulting from arbitrary yield and altitude combinations. A real gas equation of state for air and a model of the US Standard atmosphere are also included.
