FIELD: machine building.
SUBSTANCE: when making a coating for acoustical treatment for the leading edge of the inlet of a nacelle of the aircraft, comprising a reflective layer, a cellular structure and an acoustically resistive layer, first the form of cellular structure is represented in digital form. Next, the location of the first row of the first strips that do not intersect each other is determined in a virtual way, and the location of the second line of second strips that do not intersect with each other in order to determine their geometry. The first strips overlap with the second strips to form a channel between two first adjacent strips and the second two adjacent strips. Each strip is cut in accordance with their previously defined geometries. In each strip the cutouts are made to ensure connection of the strips to form a cellular structure with shapes corresponding to the front edge, and a reflective layer, and an acoustically resistive layer are installed. Other inventions of the group relate to the coating for acoustic treatment by means of the above-mentioned method and the nacelle of an aircraft, having such coating.
EFFECT: invention enables to simplify manufacture of coatings for acoustic treatment of the front edge of an air-intake of the nacelle of an aircraft.
