Internal ballistics

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 high-tech artillery.

For rocket-propelled projectiles, internal ballistics covers the period during which a rocket motor is providing thrust.^[2]^[3]
