The aircraft fuel ventilation system comprises an oil storage device and at least one ventilation pipeline, an oil storage space and an expansion space are formed in the oil storage device, the ventilation pipeline is provided with a first part and a second part, the first end of the first part is located in the expansion space, and the second end of the second part is located in the expansion space. The second end of the first part is positioned on the outer side of the expansion space; the first part is arranged in a descending trend, and the closer the first part is to the first end of the first part, the lower the first part is; the second part is arranged in a descending trend, and the farther the second part is away from the second end of the first part, the lower the second part is. The ventilation pipeline is installed at the highest point, fuel oil can be prevented from overflowing out of the oil storage device during normal operation, meanwhile, the expansion space of the oil storage device is always guided to be balanced with the atmosphere outside the aircraft during normal operation of the aircraft, and the oil storage device is prevented from being damaged due to internal and external pressure difference; the first part and the second part of the ventilation pipeline are arranged in a descending trend, so that liquid accumulation of the pipeline can be prevented.

    本申请公开了一种飞机燃油通气系统及飞机,飞机燃油通气系统包括储油装置以及至少一个通气管路,储油装置形成有储油空间和膨胀空间,通气管路具有第一部分和第二部分,第一部分的第一端位于膨胀空间内,第一部分的第二端位于膨胀空间的外侧;第一部分呈下降趋势设置,第一部分越靠近第一部分的第一端,位置越靠下;第二部分呈下降趋势设置,第二部分越远离第一部分的第二端,位置越靠下。通气管路的最高点安装,可以防止正常运行时燃油溢出储油装置,同时飞机正常运行时始终保持储油装置膨胀空间被引导与机外大气平衡,避免了储油装置因内外压差被损坏;通过通气管路的第一部分和第二部分均呈下降趋势设置,可以防止管路积液。
