Internal ballistics (also interior ballistics), a subfield of ballistics, is the study of the propulsion of a projectile.
In guns, internal ballistics covers the time from the propellant's ignition until the projectile exits the gun barrel.[1] The study of internal ballistics is important to designers and users of firearms of all types, from small-bore rifles and pistols, to artillery.
For rocket-propelled projectiles, internal ballistics covers the period during which a rocket motor is providing thrust.[2][3]
