    • Disclosed is a method for controlling the flammability of fuel vapors in an aircraft main fuel tank that is located in whole or in part in the fuselage contour. The method comprises a fuel system architecture and fuel consumption sequencing maintaining liquid fuel in said main tanks during all normal operations. Ceasing the withdrawal of fuel from the main tank when the fuel reaches a predetermined level thereby limiting the volume and flammability exposure time of the fuel vapor ullage. Once the predetermined level is met the fuel is supplied from wing tanks throughout the remainder of the mission. The predetermined main tank fuel level at which wing tank fuel begins to be consumed is determined by the aircraft flight reserves fuel volume stored in the main tank as well as the amount necessary to continuously submerge the main tank fuel pumps during the entire mission.
    • 公开了一种控制整个或部分位于机身轮廓中的飞行器主燃料箱中的燃料蒸汽的可燃性的方法。 该方法包括在所有正常操作期间在所述主油箱中保持液体燃料的燃料系统结构和燃料消耗顺序。 当燃料达到预定水平时,停止燃油从主油箱的撤出,从而限制燃油蒸汽消耗的体积和可燃性暴露时间。 一旦满足预定水平,燃油就从任务的其余部分的翼舱提供。 机舱油箱燃料开始消耗的预定主油箱燃料油位由存储在主油箱中的飞机储备燃料量以及整个任务期间连续淹没主油箱燃油泵所需的量决定。
