A Prediction Method for Blast Focusing

Abstract

The report discusses an over-pressure forecasting technique established by the Ballistic Research Laboratories (BRL) at Aberdeen Proving Ground, Md. The method involves calculating the forecast representative value of the speed of sound for azimuth angles for 1000-ft layers to 10,000 feet. Using prepared graphs, over-pressure intensity and focal points where critical over- pressure will occur are pin-pointed and semi-objectively forecast. This Note should prove beneficial to those units that are faced with providing this difficult forecast of possible damage.
