Blast Overpressure Studies. Nonauditory Damage Risk Assessment for SimulatedMuzzle Blast from a l2Omm Ml2l Mortar System

摘要

This study was undertaken to establish the subthreshold, threshold, andsuprathresholds for nonauditory injuries in a simulated muzzle blast environment like that produced when firing a 120mm M121 mortar system. A vertical axis explosively driven shock tube, in combination with reflector shields, was used to produce the required muzzle blast pressure-time pattern. Varying numbers of anesthetized sheep were subjected to 6 or 50 blasts of simulated muzzle blast
