The second phase of the dynagun firings with the improved data acquisition system, should lead to a more quantitative judgment on the dynagun reproducibility, reliability, maintainability, and ballistic correlation. In an uncertain state is the reliability of the present high pressure seal, which may eventually need some redesign, and the impact of the high heat loss. The present two grams of CBI with bagged match ignitor system for the dynagun is tolerable. The employment of a rapid-pressurization, lower ignitor load assembly would require machine redesign of the dynagun breech, and its recommendation is uncertain at this time. A more extensive series of tests with various kinds of propellant is recommended for the high pressure acoustic burner to acquire a basis for judgment on its applicability to burn rate measurement and quality in- process propellant control. The limited number of scalar gun firings prevents clear judgment on this system. The data shows favorable results and the device remains a candidate for propellant ballistic acceptance.
