The invention relates to a fuel tank venting system for an aircraft. The system includes a sump tank positioned within a fuselage of the aircraft; a main tank including separate first and second tanks positioned adjacently and spaced apart by a rib, the first tank being adjacent to the sump tank; the ventilation oil tank is located on the outer side of the second oil tank, is independent of the second oil tank and comprises an air inlet; the first ventilation pipeline is communicated between the second oil tank and the ventilation oil tank, so that air can enter the second oil tank from the air inlet through the first ventilation pipeline; a second vent line located below and independent of the first vent line and communicating between the second tank and the vent tank, the second vent line including a valve; and a third vent line independent of the first vent line and the second vent line and communicating between the second tank and the vent tank through the rib.

    本发明涉及一种用于飞机的燃油箱通气系统,该系统包括定位在飞机的机身内的集油箱;包括独立的第一油箱和第二油箱的主油箱,第一油箱和第二油箱相邻地定位并由肋部间隔开,第一油箱与集油箱相邻;位于第二油箱的外侧并独立于第二油箱的通气油箱,该通气油箱包括进气口;第一通气管路,该第一通气管路在第二油箱与通气油箱之间连通,使得空气能够从进气口经由第一通气管路进入第二油箱;第二通气管路,该第二通气管路位于第一通气管路下方并独立于第一通气管路,并且在第二油箱与通气油箱之间连通,第二通气管路包括阀;以及第三通气管路,该第三通气管路独立于第一通气管路和第二通气管路,并且穿过肋部在第二油箱与通气油箱之间连通。
