Sensitivity Study of Rifle Gas Systems
Abstract
Results of a sensitivity study of the M-16 rifle gas system are presented; this study is based on a simulation of rifle gas system operation developed in the BRL. The calculations indicate that thermodynamic variables in the bolt carrier cavity are only weakly sensitive to variations in the following parameters: pressure and temperature in the gun barrel when the bullet passes the port, friction in the duct flow, and frictional resistance to motion of the bolt carrier. The computational results are sensitive, however, to the chosen origin of time on the oscillogram showing barrel pressure at the port station. Graphs are presented for a typical round illustrating pressure, temperature, density, and piston motion histories for M-16 and AR-18 rifle gas systems.
