A device for de-icing an aerodynamic profile (100), said device comprising a surface, referred to as a lower surface, a plurality of unitary cavities (2a, 2b) delimited by a partition grid (3a, 3b) on said surface, and a barrier arranged on said partition grid wherein said surface comprises a first plurality of holes (5) and a second plurality of holes (6), the first plurality of holes connect the single cavities to means for simultaneously generating a negative pressure in the cavities in order to press the barrier onto the partition grid, and the second plurality of holes connect the single cavities to means for generating one or more pressure pulses in at least some selected single cavities, wherein the barrier is equipped with one or more resistive networks (8) positioned below the barrier and aligned with some of the cells (2b, 2c) in order to create a localized electro-thermal de-icing zone in the device.
一种用于对空气动力学轮廓(100)进行除冰的装置,所述装置包括称为下表面的表面、由所述表面上的分区网格(3a、3b)界定的多个单一空腔(2a、2b)以及布置于所述分区网格上的屏障,其中所述表面包括第一多个孔(5)和第二多个孔(6),所述第一多个孔将所述单一空腔连接到用于同时在所述空腔中生成负压的装置以便将所述屏障压到所述分区网格上,所述第二多个孔将所述单一空腔连接到用于在至少一些选定单一空腔中生成一个或多个压力脉冲的装置,其中所述屏障配备有一个或多个电阻网络(8),所述一个或多个电阻网络定位于所述屏障下方且与所述单元(2b、2c)中的一些对齐以便在所述装置中创建局部化的电热除冰区。
