Product Overview:
The Helium Storage Tank BL01-001 is fitted to the mass spectrometer instrument pack for the Ptolemy experiment on the Rosetta mission.

The tanks are ‘sealed for life’ storing Helium gas for a period of up to 12 years until Rosetta reaches its destination. Ptolemy will use the helium in two gas experiments once the lander touches down.

The unit is a lightweight welded Titanium pressure vessel which releases gas on a command to a mechanical rupture valve.

The pressure vessel comprises a titanium pressure vessel, a frangible pillar an expanding plug to seal the vessel after charging, plus a welded in blanking plug to provide a secondary seal. The internal volume of the vessel has been maximised and the mass minimised.
