Abstract: A drainage mast able to drain effectively the liquid contained in the compartment of an aircraft when the pressure within the compartment is lower than the outside pressure without using any pressure control active device and without causing any significant perturbation to the aerodynamic behavior of the aircraft. The drainage mast is configured with a cross section area decreasing from its entry section to the compartment to its outlet section and is disposed at an acute angle α relative to the compartment in the airflow direction. The entry and outlet sections have two perpendicular symmetry axes of different length, the entry section is arranged with its longer axis of symmetry substantially parallel to the airflow direction. The drainage mast has a symmetrical configuration with respect to a plane substantially perpendicular to the fuselage envelope passing through the longer axis of symmetry of the entry section.

Abstract translation: 当排气室内的压力低于外部压力时，不使用任何压力控制有源装置并且不会对飞行器的空气动力学行为产生任何明显的扰动，排水桅杆能够有效地排出飞机内部所含的液体。 排水桅杆构造有从入口部分到隔室到其出口部分的横截面面积，并且相对于隔室在气流方向上以锐角α设置。 入口和出口部分具有不同长度的两个垂直对称轴，入口部分布置成具有与气流方向基本平行的较长对称轴。 排水桅杆相对于基本上垂直于通过入口部分的较长对称轴的机身外壳的平面具有对称的构造。
