Abstract
【解決手段】航空機の燃料タンク区画60内に一対の翼タンク40と中央タンク45とが設けられ、互いに連通している。翼タンク40はサージタンク35を介して外気に開放されている。不活性ガスとして窒素を多く含むNEAが、NEA供給源15からバルブ25,30を介して導入される。外気圧力が上昇する航空機の下降中には、バルブ30を介して混合チャンバ55へNEAが導かれ、外気と混合して翼タンク40さらには中央タンク45に導かれる。外気圧力が相対的に低くなる上昇中あるいは巡航中には、バルブ25を介して中央タンク45にNEAが導かれ、さらに翼タンク40へと流れる。これにより、タンク40,45全体の酸素濃度が適切なものとなる。
