Datasheet

2021 Nammo Raufoss Aluminium Propellant Tank

The inherent risk of non-demisable Titanium Alloy tanks surviving re-entry and falling to Earth is recognised.  Nammo Space has utilised specially developed forging and friction stir welding capabilities at its Raufoss manufacturing facility to create spacecraft propellant tanks in Aluminium Alloy.

Nammo’s metallurgists and chemists have carried out analysis and propellant compatibility testing of high strength Aluminium alloys with hydrazine derivatives, NTO and Hydrogen Peroxide.  Using the alloys that pass the selection and mechanical performance criteria, tank shells are forged, machined and assembled with moulded diaphragms and appropriate welding techniques.  The tanks are then proven through a complex and intensive inspection and testing regime, before being delivered for propulsion system integration.

Performance Characteristics

  • Storage Fluids 87.5% H2O2, MON, MMH
    Compatibility testing is available for other fluids.
  • Pressurant Nitrogen
    Helium gas can also be used
  • Tank Type Positive Expulsion Device (Diaphragm type)
  • Useable Propellant Volume 45.5 Litres
  • Mass < 13 kg
  • Maximum Expected Operating Pressure 32 bara
  • Proof Pressure Factor 1.5
  • Burst Pressure Factor > 2
  • Expulsion Efficiency > 99%
  • Blowdown Ratio 2.7
  • Tank Form Spherical domes with cylindrical mid-section
  • Dimensions (at interfaces) ø490 mm x H 650 mm
    Equatorial mounting
  • External Leakage 1 x 10-6 scc/s
  • Diaphragm Material Viton
  • Tank Structure Material AA6000 series T6
  • Structural Interface Equatorial adapters
    Interfaces are customisable, please contact Nammo for further details.
  • Fluidic Interface ½” tube stub (propellant side), ⅜” tube stub (gas side)
    Interfaces are customisable, please contact Nammo for further details.
  • Operational Cycles > 10
    Expulsion cycles
  • Technology Readiness Level TRL5

Status
