The ogival nose fairing protects the payloads during the atmospheric flight phase (acoustic
protection on lift-off and during transonic flight, aerothermodynamic flux).
A long pattern fairing is used for this mission. It has a height of 17 m and a diameter of 5.4 m.
The fairing structure includes two half-fairings comprising 10 panels. These sandwich panels
have an expanded aluminium honeycomb core and two carbon fibre/resin skins.
The fairing is separated from the launcher by two pyrotechnic devices, one horizontal (HSS)
and the other vertical (VSS). The vertical device imparts the impulse required for lateral
separation of the two half-fairings
The fairing has been coated with a new FAP (Fairing Acoustic Protection) product since flight

Z tego też co widzę, to owiewka jest chyba z aluminium...
