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 ]
Internal ballistics: A subfield of ballistics, that is the study of a projectile's behavior from the time its propellant's igniter is initiated until it exits the gun barrel. The study of internal ballistics is important to designers and users of firearms of all types, from small-bore Olympic rifles and pistols, to high-tech artillery.
In internal ballistics terms, if the base of a projectile is thought of as a piston propelled by the expanding gas, then as barrel length increases the volume swept by the piston also increases, and hence the amount of energy that can be extracted from the gas's burning increases. A longer barrel allows more propellant to be used: the ...
