A Comparison between Experiment and Simulation for Concept VIC regenerative Liquid Propellant Guns. 3. 155 mm
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 155 mm gun fixture labeled Gun 1, an experimental fixture planned as the forerunner of the final design. Previous reports discussed the 30 mm gun fixtures. The 155 mm Concept VIC gun design is described together with a brief discussion of the 155 mm test program. Three charge sizes of 2 liter, 5 liter and 7 liter were tested with two igniters, a one-stage solid propellant igniter and a two-stage solid and liquid propellant igniter. The experimental data are analyzed, and the model is compared to experiment. The process of choosing input values for the gun code is discussed in detail. The result is in excellent agreement with all the experimental data. (edc)
