A vent trunk (100) extending from a left vent tank (10) across a longitudinal plane of symmetry of an aircraft across a wing via a central wing tank (20) to a right vent tank (30), and in fluid communication with the left vent tank (10) and the right vent tank (30) at left and right ends, respectively; the ventilation branch is branched from the ventilation main pipeline (100), leads to the interior of the central wing oil tank (20) and is in fluid communication with the interior of the central wing oil tank (20) through a tail end opening, and the pipeline cross section area of the ventilation main pipeline (100) is larger than that of the ventilation branch. The aircraft fuel tank ventilation system has the anti-crosswind function, and the airworthiness of an aircraft can be enhanced.

    一种通气干道(100),所述通气干道(100)从左通气油箱(10)起穿过飞机的纵向对称面横贯机翼经由中央翼油箱(20)延伸至右通气油箱(30),且分别在左右两端与所述左通气油箱(10)和所述右通气油箱(30)流体连通;以及通气分支,所述通气分支从所述通气干道(100)上分叉而通向所述中央翼油箱(20)内部并通过末端开口与所述中央翼油箱(20)内部流体连通,其中,所述通气干道(100)的管路横截面积大于所述通气分支的管路横截面积。本发明的飞机燃油箱通气系统具有防横风功能,能够增强飞机适航性。
