FIELD: machine building.
SUBSTANCE: coating for acoustic treatment applied on the front edge of an air intake of an aircraft gondola, comprises an acoustically resistive layer, a cellular structure and a reflecting layer. The cellular structure comprises many channels, exiting at one side at the level of the first surface and at the other side - at the level of the second surface. The cellular structure comprises cuts or holes arranged at the level of side walls of several channels, making it possible to establish communication between adjacent channels so that a network of communicating channels is established to isolate one or a group of non-communicating channels. At least one of communicating channels is connected with a hot gas input. The other inventions of the group relates to a front edge of an aircraft and an air intake of an aircraft gondola, comprising the above coating for acoustic treatment.
EFFECT: inventions make it possible to join a coating for acoustic treatment with an anti-icing system.
