FIELD: transport. ^ SUBSTANCE: invention relates to aircraft engineering, particularly, to power plant air intake and aircraft sound-absorbing coating. Said coating may close air intake front edge and comprises, on one side, reflecting layer extending from inside to outside, cellular structure and sound-absorbing structure. On the other side, coating incorporates ice processing system made up of heating layer containing open zones to transmit acoustic waves. Sound-isolation structure comprises structural layer with holes. Note that heating layer is located under said structural layer. ^ EFFECT: better sound absorption and anti-icing protection. ^ 10 cl, 22 dwg |
