Vented Bomb Tests to Characterize Propellant and Combustible Case Extinguishment

摘要

A study was conducted at Safety Consulting Engineers, Inc. to simulate ballistic cycle pressure reduction and its effect on propellant and unpredictable combustible cartridge case (CCC) residue development. A new vented bomb system was developed and designed to simulate a 120 mm propellant/combustible cartridge base ballistic environment to 80,000 psi pressure and associated ballistic times. Full-diameter burst discs were used to suddenly reduce pressure to atmospheric level. Numerous tests were conducted monitoring chamber pressure time. Residuals, if any, were collected after extinguishment.
