What is the maximum speed at which the gases from an RPG-7 explosion can expand?

The maximum speed at which the gases from an RPG-7 explosion can expand is approximately 19,067 feet per second (FPS). This figure reflects the high velocity at which the combustion gases from the rocket propel out of the weapon once fired. In the context of an RPG-7, the speed is influenced by the chemical reactions occurring in the propellant, which rapidly generate a large volume of high-temperature gases.

Understanding this maximum speed is crucial for both operational effectiveness and safety considerations, as it helps to define the effective range and impact capabilities of the RPG-7. Knowledge of the gas expansion speed allows operatives to anticipate the behavior of the weapon during deployment, including the range it can effectively engage targets and the consideration of backblast hazards to personnel and equipment situated behind the launch point.
