FIELD: prevention of ice formation; aviation.
SUBSTANCE: design of a compact input device including one partition and / or an acoustic panel extending into the nacelle edge region to reduce noise. Compact input device is used with low-energy anti-icing system based on fluid medium, made with possibility to prevent formation of ice on acoustic panel in area of nacelle edge. Porous panel is combined with cover of inlet edge; wherein low-temperature fluid medium based on glycol for anti-icing protection penetrates through porous panel on outer surface of cover of inlet edge with subsequent passage backwards along air flow to acoustic panel and thereby prevents formation of ice on the porous panel and reduces or prevents formation of ice on the acoustic panel.
EFFECT: technical result is that thermal protection is not required.
