Gun Muzzle Blast Field: A Computational Method Based on the Unified Theory of Explosions.

摘要

A computational method of Henriksen and Cummings based on Porzel's Unified Theory of Explosions has been extended to permit calculations of the blast field in the region behind the muzzle exit plane,and uses a different method for the prediction of overpressure pulse lengths. Predictions based on the theory were compared with experimentally determined values of overpressure and pulse lengths for guns from 8inch diameter to .30caliber. The theory was found to be adequate for the calculation of gun muzzle blast over a wide range of gun sizes. A simple BASIC program listing is provided for the computation of gun muzzle blast fields.
