Abstract
Regenerative liquid propellant gun (RLPG) technology is sufficiently mature to allow the testing of the first 155 mm liquid propellant gun. In support of the development of this artillery weapon, test fixtures in 30 mm and 105 mm sizes have been built and fired. This report describes the analysis and modeling of the 105 mm gun fixture. A previous report discussed the 30 mm gun fixture, and a future report will concentrate on the 155 mm gun. The model is first benchmarked against a series of long charge firings. The process of choosing input values for the gun code is discussed in detail. The model is then used to predict the performance of a medium charge firing and a short charge firing. Finally, further analysis of the data is presented in which assumptions governing the selection of values for the empirical parameters are modified. (jhd)
