The invention relates to a micropore seepage structure, an airplane anti-icing system and an airplane. The microporous seepage structure includes: a first panel including a plurality of micropores; asecond panel connected with the first panel, wherein a liquid storage cavity is formed between the first panel and the second panel, and an anti-icing liquid inlet is formed in the second panel; and adamping diaphragm arranged on the inner wall of the first panel and covering the multiple micropores, wherein, when the temperature is below 0 DEG C, the damping diaphragm generates a pressure difference of a preset value on the two sides. Ice prevention is conducted through micropore leakage, the operation energy consumption of the airplane anti-icing system is low, and the aerodynamic effect ofthe airfoil profile cannot be affected.
本申请涉及一种微孔渗液结构、飞机防冰系统及飞机。微孔渗液结构包括:第一面板,包括多个微孔;第二面板,连接第一面板,第一面板与第二面板之间形成储液腔,第二面板上设置防冰液入口;阻尼膜片,设置于第一面板的内壁,覆盖多个微孔,在0℃以下时,阻尼膜片在两侧产生预设值的压差。本申请通过微孔渗漏进行防冰,飞机防冰系统运行能耗低,不会对翼型的气动效果产生影响。
