우주비행체 지상검증 시뮬레이터용 추력기 개념 설계

For attitude control and movement of the spacecraft simulator on the ground environment, it use cold gas propulsion system in general. Cold gas propulsion system is a core component of the attitude control and movement of the simulator. This system obtain a thrust by supplying the stored gas which to the thruster that a tank stored high pressure inert gas through regulator. In this study, after deriving the key design parameters to satisfy the required specifications by using the formula isentropic one-dimensional nozzle flow, designed thruster conceptual design and configuration using a CAD program.
