Pressure-Flamespread Correlations in the Simulator Ignition Studies of 105-mm Tank Charges
Abstract
Ignition diagnostics via a transparent gun chamber simulator have become an integral part of efforts in the development of advanced tank gun charges at the US Army Ballistic Research Lab. The diagnostics provide insights into the ignition processes occurring during the early phase of the interior ballistic cycle. In the studies, the pressure and photographic data obtained are the most important in analyzing the functioning of the ignition system, the ignition of propelling charges, and the formation of pressure waves. In the present study, we established close correlations between these two kinds of data. The correlations can help one better understand the physical phenomena, the pressure distribution and flamespreading in particular, occurring in the 105-mm tank gun chamber. Furthermore, the correlations can enable one to visualize the flamespreading by examining the pressure-time curves alone and vice versa in many cases. In addition, effective ignition of propellant is characterized and the effects of apparent ullage appearing in a cartridge on the early phase of the ignition processes are discussed.
