DeflagrationA deflagration is a relatively slow explosion,
generating only subsonic pressure waves. This sort of explosion
is usually produced by rapid chemical combustion reactions, for
instance of gunpowder in a firearm, or fuel in an internal
combustion engine. Contrast detonation, where the pressure waves
are supersonic. Deflagrations are easier to control than
detonations, and better suited when the goal is to move an
object (a bullet in a gun, or a piston in an engine) with the
force of the expanding gas. This article is a stub. You can help
