COATING FOR ACOUSTIC TREATMENT INCLUDING FUNCTION FOR HOT AIR PROCESSING OF ICE CRUST Russian patent published in 2013 - IPC B64D33/02 B64D15/04 F02C7/47

Abstract RU 2471680 C2

FIELD: transport.

SUBSTANCE: coating is designed for acoustic treatment at the level of airborne vehicle surface. The coating contains acoustically resistive layer (28), cellular structure (30) and reflecting layer (32). Between cellular structure and acoustically resistive structure, channels (34) are located, each one of which is bounded by wall (36) other than walls of cellular structure, and one of channel ends is connected with hot air inlet.

EFFECT: compatability of coating with acoustic treatment and hot air processing of ice crust.
