Abstract
Nowadays in aircraft so-called on-board inert gas generation systems (OBIGGS) are used to generate inert gases, to which OBIGGS cooled bleed air of engines or auxiliary power units is fed. According to an embodiment of the present invention, an air cooling device for an OBIGGS system in an aircraft is proposed that comprises a bleed position. By way of the bleed position, cooling air from an air conditioning unit on board the aircraft can be bled, which cooling air can subsequently be used for cooling supply air for the OBIGGS system. Thus, there is no need for an additional ram-air inlet channel for cooling the supply air. Air resistance and weight are thus reduced, and the stability of the primary structure is enhanced.
