High Velocity Firings of Slug Projectiles in a Double-Travel 120-MM Gun System

摘要

Test firings were planned and executed by the Interior Ballistics Division (IBD)of the Ballistic Research Laboratory (BRL) to support high velocity, scaled projectile firings for the Terminal ballistics Division (TBD) of BRL. IBD conducted a computer evaluation of gun propellants available to TBD using the interior ballistic code IBHVG2, then verified the results with a series of slug projectile firings at BRL's Sandy Point (Range 18) large caliber firing facility. Interior ballistic results from the computer evaluation were compared with corresponding data from the slug firings and the first series of scaled projectile firings conducted by TBD.
