Ariane tanks  [ Return towards  Equipment  ]

Ariane IV Tanks
With its 8.2 metric tons of liquid hydrogen and liquid oxygen, the propellants tanks of the third stage of Ariane 1 - carried a satellite weighing 1,850 kg.

The tanks on the Ariane IV, loaded with an extra 3.6 metric tons of propellants, carried a 4,700 kg payload and underwent twice the lift-off thrust. Yet it weighs only 110 kg more, and it cost only half as much as the previous model. Our experienced teams managed to achieve this progress while ensuring a constantly high level of quality.

Ariane V Tanks
The oxygen tank of new-generation Ariane V launch vehicle is pressurized by a liquid helium subsystem designed and manufactured by Air Liquide and containing 1,100 liters of fluid.

Compared with pressurization by oxygen, the mass saving achieved by this vacuum-insulated tankallowed the launch vehicle's payload to increase by more than 200 kg.
We are also joining forces with EADS-LV in Cryospace GIE, taking part in the development and production of the main stage cryotechnical tank for Ariane V.
