A device deices an aerodynamic profile that has a lower surface, a plurality of unitary cavities delimited by a lattice of partitions on the lower surface, and a barrier arranged on the lattice of partitions. The surface includes a first plurality of holes which connect the unitary cavities to a device for generating a negative pressure in the cavities simultaneously so as to press the barrier onto the lattice of partitions. A second plurality of holes connect the unitary cavities to a device for generating one or more pressure pulses in at least some of the selected unitary cavities. The barrier is equipped with one or more resistive networks positioned below the barrier in line with some of the cells in order to create localized electrothermal deicing zones in the device.
