Planned implementation July 1976 of Continuous Cannon Propellant production at Radford AAP has generated requirements for on-line ballistic evaluation of charge density, so loading can occur shortly after manufacture. Presently, loading density determination is made by confirmatory ballistic firings with use of a reference propellant lot, and a time delay of several weeks. Establishment of an on-site proving ground capability at a manufacturers plant presents many undesirable features. The alternate solution to on-site proving ground capability was determined to be a laboratory ballistic simulator, or as a minimum, a scaled-down gun which would fire inert slugs, and which was small enough to be fired in a test tunnel of minimum sophistication. This report analyzes three current approaches for duplicating large caliber interior ballistics with experimental variable volume testing devices, namely, the Eglin AFB Scalar Gun, Picatinny Arsenal Hydrogun, and University of Illinois Dynagun.
