Boeing Commercial Aircraft has selected Liebherr-Aerospace Toulouse SAS, Toulouse (France), to design, develop, supply and service the Nitrogen Enriched Air Inerting System (NEAIS) regulation valves for the KC-46 Tanker Program. The KC-46A aircraft is a multi-role tanker derivative of Boeing’s successful 767 Program. Boeing has been selected by the US Air Force to deliver 179 of the next-generation aerial refuelling tankers. The airplane will feature additional systems compared to the Boeing 767, most notably additional fuel tanks and related safety systems. The regulation valves monitor the air ducted to the system that inerts the fuel tanks as fuel is gradually leaving the tank in order to prevent fuel fume-igniting conditions.
