Projectile Features that Affect Empirical Interior Ballistic Analysis

Top Back Next

Several Empirical Interior Ballistic inputs are calculated by Mass Properties based on the model. For our example we get the following data from Mass Properties:

Projectile Mass
Propellant Mass since there is a Propellant Component Defined.
Propellant Volume since there is a Propellant Component Defined.

Empirical Interior Ballistics is commonly run without modeling either the case or propellant. If you do model the case and or propellant then mass properties calculates the propellant volume, which can be copied in as the chamber volume. Since the chamber volume is hard to measure, this is a great way to get an accurate value. Our example projectile does have both the propellant and case modeled.
