Abstract:To reduce the volume and mass of pressurized system in the upper stage of launch vehicle and spacecraft, a new light-duty pressurization system with master and secondary constant pressure control pipe was designed in this paper. The system could use of the gas in the bottle as could as possible. It had the redundant pressurized structure that heightened the system reliability. The pneumatic isolating movable valve was adopted to suit multiple start-up. The system structure was simple. The results of the test and real flying showed that the master and secondary pipe of the pressurization system worked in harmony. The system response was quick and system performance was stable and reliable.
Keywords:Vehicle carrier  Spacecraft  Pressurization system  Constant pressure control pressurization
