N2  - Abstract. Cold gas propulsion systems have relatively lower technologies in comparison to other propulsion systems and cost less than them. In this study, for a titanium alloy structure which uses nitrogen gas, first, a blowdown propulsion system without a regulator (pressure controller) was designed, and the minimum mass quantity of the whole system was calculated using genetics algorithm based on the design variables. Given the facts that: 1) the equipment placed after the regulator do not need to be very powerful, so they are lighter; 2) systems which do not have regulators should have a total impulse equal to the system with regulators under the same conditions and, therefore, should have a higher pressure and more primary propellant in the tank, a system with a regulator was designed in order to observe if the weight of the regulator and the conditions of such systems could overcome these two conditions.
