Prediction of interior ballistic parameters of gun and mortars

Use the interior ballistics analysis to:

• Determine muzzle velocity and maximum pressure in gun or mortars
• Trade-off propellant weight versus projectile weight in gun or mortars
• Estimate the effects of propellant blending in gun or mortars

The Interior Ballistics analysis calculates the velocity, breech and base pressure, linear accelerations of the projectile during travel down the barrel. A blend of up to three propellant types can be simulated.

Reference libraries are included with detailed information on propellant geometry and burn characteristics as well as igniter and gun parameters. This information can be retrieved quickly for use in analyses.

Program IBGUN should enable:

• The Interior Ballistics analysis calculates the velocity, breech and base pressure, accelerations of the projectile during travel down the barrel, using model STANAG 4367, Edition 2, Termodynamic Inetrior Balistic Model with Global Parameter
