Xenon Regulator & Feed System

Description

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).

 

Redundancy

The XRFS provides a high degree of redundancy (series and parallel) and failure tolerance, to ensure reliability and functional performance throughout an entire  mission.

 

Main Components

The main components of the XRFS are:

 

 

 

Xenon Pressure Regulator Characteristics
Regulator Type
"Bang-bang" type regulator (pulsing valves) with two parallel redundant regulation branches, each branch being twice redundant.
Flow Control
The maximum possible flow rate is limited by upstream pressure and smallest diameter in the system's flow path. The actual flow is controlled by regulation of the pressure within the plenum.
Inlet Pressure
3 to 120 bar
Outlet Pressure
2.65 bar ± 0.2 bar
External Leakage
< 1x10-6 scc/s GHe
Internal Leakage
< 2x10-4 scc/s GHe
Flow Rate
> 6 mg/s gaseous xenon
Flow Restrictor
46800 Lohms
Total propellant throughput
300 kg max
Mass
< 5.9 kg
Dimensions
443,5 mm x 278 mm x 228 mm (plenum)
Temperature Range
27 C° to 45 C° (operating)
Design Life
15 years
Cycle Life
1,000,000 qualified
Reliability
> 0.998
