Projectile Ullage Inspection Technique: Laboratory Demonstration Apparatus.

摘要

A simple, nondestructive, noncontaminating technique for the inspection of assembled projectiles for minimum ullage (internal free volume) is presented. The technique is based on the use of ideal gas formulas and the change in the pressure of a system that results from known change in the system volume. The laboratory demonstration apparatus based on the technique is described. Suggestions for application of the technique in a production facility are presented.
