Application of the Industrial CT Technology in the Ammunition Charge Density Difference Measurement

This paper introduces two kinds of methods for the testing of the density resolution of the BT-400 type industrial CT nondestructive testing system. The density resolution of the system is about 1.0%, and the measurement of one warhead charging density difference is completed by the industrial Ct equipment. The results and the sample open shell drainage method results are compared. The charge density error is less than 1%, the density difference is consistent in magnitude. It shows that the density difference measurement method is feasible by industrial CT technology, the measurement results are reliable. It has some reference significance to the reader.
