FIELD: transport.
SUBSTANCE: invention relates to isolation structure for aircraft heat and sound isolation, its application in aircraft and aircraft with such structure. Said isolation structure has heavy layer and extra absorbing layer. Said heavy layer is perforated in some zones. Fraction of holes surface is kept to make said heavy layer in fact a sound-conducting at frequencies below that of dual wall of isolation structure. Said dual wall is formed by aircraft outer skin and said heavy layer.
EFFECT: efficient isolation.
