FIELD: aeronautical engineering; air intakes.
SUBSTANCE: proposed air intake has circular duct (1), flow divider (5), cleaned air outlet passage (6), outlet passage (7) for discharge of foreign matter and dustproof device which is mounted at point of bend of passage on its internal wall (3); dustproof device is circular in form and is provided with doors. Doors (4) overlap each other in closed position and copy the form of internal wall of passage; in open position, doors form fan-type structure mounted at angle relative to internal wall of passage in way of flow; angle of doors does not exceed 70° which is necessary for change of shape of profile of circular passage and for direction of foreign matter to discharge passage.
EFFECT: enhanced operational efficiency of protection of aircraft engine against penetration of foreign matter.
