Xenon Regulator & Feed System
The XRFS is a 'bang-bang' pressure regulator designed mainly for helium and xenon gas. This type of regulator is typically used in ArianeGroup's Radio Frequency Ion propulsion systems.
The regulator incorporates a system of valves, a plenum volume, pressure transducers and flow restrictors. The main function of the regulator is to down-regulate high pressure xenon propellant from a storage tank to the supply pressure required by a Xenon Flow Controller (XFC).
The XRFS provides a high degree of redundancy (series and parallel) and failure tolerance, to ensure reliability and functional performance throughout an entire mission.
