An Analysis of Local Temperature Profiles Encountered in the Aluminum Cartridge Case Drilled Hole Experiment

Abstract

The consequence of propellant gas flow through a split in the cartridge case sidewall is usually more serious with aluminum cases than it is with brass cases. In order to gain a better understanding of the failure phenomenon experienced with aluminum cases, a combination experimental and theoretical program was initiated to study the failure dynamics using intensionally induced failures. This report covers only the surface temperature history of a drilled hole as function of time and propellant gas flow. An analytical model was constructed from existing solutions to previously well investigated phenomena.
