A solid propellant gas generator releases a flowing mixture from a solid propellant, separated from a surrounding area, into the surrounding area. The solid propellant gas generator includes a cooling system for cooling the flowing mixture. The cooling system has at least one feed device for feeding a gas from the surrounding area to the flowing mixture in order to mix the flowing mixture prior to entering into the surrounding area with the gas from the surrounding area.
