internal ballistics

Internal ballistics, also known as interior ballistics, is a branch of ballistics that focuses on the events occurring inside a gun barrel. It specifically examines the combustion of gunpowder, the resulting pressure development, and the motion of the projectile as it travels along the bore. This process involves the conversion of the chemical energy of a propellant into the kinetic energy of a projectile. When a propellant is ignited within a confined space, the hot gases produced increase pressure, which then propels the projectile. The study of internal ballistics is crucial for understanding how firearms and rocket motors function.12
