FIELD: transport.
SUBSTANCE: invention relates to aircraft anti-icing systems. Aircraft nacelle comprises assembly of turbojet air intake leading edge 1, inner surface 9, outer surface 11, and anti-icing means including anti-icing coat 133 applied on part of outer surface 11. Bonding matrix of said coat 13 comprises, at least, one piezoelectric active element. Piezoelectric actuators comprise, at least, one piezoelectric active element 21 engaged with inner surface and electric power feeder 23. Said piezoelectric active element 21 comprises cylinder and vibrator. Anti-icing coat material represents polyurethane or fluoropolyurethane dyes, resins or plastics containing Teflon. Thickness e of anti-icing coat 13 makes 20 to 100 mcm.
EFFECT: efficient protection against icing.
