Interior | Ballistics

: Often coupled with ballistic codes to study how the physical structure of the barrel deforms under pressure.

: Once pressure exceeds the "shot-start" resistance, the projectile begins to move down the barrel. Propellant continues to burn, and gas volume increases as the projectile accelerates. Interior ballistics

The entire process occurs in milliseconds and is typically divided into three distinct stages: : Often coupled with ballistic codes to study

Several variables determine how effectively a projectile is launched: Interior ballistics

: Simplified "zero-dimensional" codes (like IBHVG2 ) that calculate average pressure and velocity. They are fast and ideal for initial design.

: The ratio of the propellant volume to the total chamber volume; higher density generally leads to more uniform burning.
