Available in PDF, EPUB and Kindle. Book excerpt: A research program was conducted to determine the causes of variability in GAU-7/A telescoped ammunition featuring molded grain propellant and a combustible case. The approach to the problem took the form of a coordinated analytical/experimental effort. a computer simulation of the GAU-7/A round was formulated, coded, debugged, validated and used to help determine the sensitivity of ammunition parameters. The experimental effort generated empirical inputs and functions for use in the model as well as defining and providing insight into the variability problem. The results of this program indicate that (1) inconsistent grain breakup (primarily the aft grain), (2) poorly performing and variable ignition components, and (3) interaction of these with a combustible case and other components easily influenced by moisture are primary contributors to GAU-7/A telescoped ammunition performance variability.
