PURPOSE: A gas generator without generation of erosive burning is provided to remarkably reduce flow velocity of combustion gas inside a grain because the combustion area inside the grain is reduced by arranging multiple propellant grains in several rows inside a combustion pipe. CONSTITUTION: A gas generator without generation of erosive burning comprises a combustion pipe(101), a nozzle structure(102), an igniter(103), a retainer(104), and multiple propellant grains(110). The nozzle structure is coupled to a downstream end where combustion gas is exhausted among both ends of the combustion pipe. The igniter is embedded in an upstream end of the combustion pipe. The retainer is embedded in the upstream end of the combustion pipe to support the igniter. The multiple propellant grains are arranged in several rows inside the combustion pipe to prevent erosive burning.
