GST 3 climate control system for the Ariane 5 rocket

GST3, a new climate control system for the Ariane 5 rocket



The GST3, Groupe Servitude de Transfert, is an independent installation which acclimatizes the nose of the Ariane 5 when it is being transported from the BAF (Bâtiment d’Assemblage Final) to the launch platform. That takes place the day before the launch.

The GST3 is composed of several overlapping climate control systems which allow a thrust of 722m3/h with a x<5,5g/kg dry air. Not an easy job if knowing that the local temperature is on average 32°C with a humidity of 85%.

The GST is the result of a perfect cooperation between Cofely Axima and Cofely Fabricom Industrie Sud.
