摘要：

FIELD: engine building.;SUBSTANCE: invention relates to air intakes of aircraft engines. Air intake of airplane comprises curvilinear air channel (1). Plate (5) is installed along width of channel (1) along its central line, at least in point of bend of channel (1). Plate (5) is installed along length of channel (1) in range from 0.25 L to 1 L, where L is length of channel (1), with shift relative to central line of channel (1) at distance ±0.15 of diameter D of inlet (4) into engine. Plate (5) is made using sound-absorbing material, has constant thickness of main part and smoothed (rounded) profiles of front and / or rear ends.;EFFECT: invention improves
