Zusammenfassung:PROBLEM TO BE SOLVED: To provide a fuel system of an aircraft, which has a ventilation function and secures explosion-proof performance without increasing the supply capability of nitrogen rich gas.SOLUTION: A fuel system 10 comprises: fuel tanks 30L, 40L, 40R, 30R; a nitrogen rich gas supply system; a left ventilation route 10L extending from a ventilation duct 11 to a fuselage 2 and communicating with the insides of the fuel tanks 30L, 40L; and a right ventilation route 10R extending from the ventilation duct 11 to the fuselage 2 and communicating with the insides of the fuel tanks 30R, 40R. The fuel tank 40L communicating with the left ventilation route 10L and the fuel tank 40R communicating with the right ventilation route 10R are divided by a central wall 15C. The fuel tanks 40L, 40R communicate with each other via fuel passage 16 and float valves 12, 12 which allow only fuel of fuel and gas to pass. 【課題】ベンチレーション機能を備える航空機の燃料システムにあって、窒素富化ガスの供給能力を上げることなく防爆性能を担保するシステムを提供する。【解決手段】燃料システム10は、燃料タンク30L,40L,40R,30Rと、窒素富化ガス供給システムと、通気ダクト11から胴体2へと延出し、燃料タンク30L,40L内と通じる左通気経路10Lと、通気ダクト11から胴体2へと延出し、燃料タンク30R,40R内と通じる右通気経路10Rと、を備える。左通気経路10Lと通じる燃料タンク40Lと、右通気経路10Rと通じる燃料タンク40Rとは、中央壁15Cにより仕切られる。燃料タンク40L,40Rは、燃料およびガスのうち燃料のみを通過させる燃料路16およびフロートバルブ12,12を介して連通する。【選択図】図2
