dc.description.abstract | The purpose of a gun bore evacuator on the turret-mounted gun barrel is to prevent the entry of the gaseous products of gun propellant combustion into the turret compartment of the vehicle after the breech block opening. The mathematical
model which takes into account all of the main parameters influencing the pressure
change inside the cylinder of the evacuator was developed. Differential equations
that describe the flow field through the nozzle in the barrel wall and in the cylinder
of the evacuator were solved numerically. Furthermore, the numerical simulations
were performed using the ANSYS FLUENT in order to analyze the phenomena
occuring in the evacuator during the charge and discharge cycles which are difficult to be taken into account with the analytical model. Aforementioned simulations were performed with the 3-D model of the evacuator and with the initial and
boundary conditions obtained from the interior ballistic calculations. In order to
find the change of the static pressure in the cylinder of the gun bore evacuator, the
experimental research was performed. The comprehensive comparison between
the numerical results and the experimental data has shown good agreement. Based
upon this analysis, the influence of the evacuator’s main design parameters on the
pressure distribution and the temperatures in the critical zones was determined.
The influence of the propellant’s initial temperature on the pressure and wall temperatures in the evacuator was also analyzed, due to the wide range of gun operating temperatures and the possibility of erosion occurrence | sr |
