FIELD: engines and pumps.
SUBSTANCE: combustion air supply device to the engine containing air inlet channel (4) that passes between outer surface (5) of aircraft and engine (3a, 3b) located in inner area; at that, air inlet channel (4) begins from air inlet holes (2a, 2b) located in the area of outer surface (5). At that, in order to implement the concept of two travelling air flows, at least one additional air inlet channel (8a, 8b) goes from the other point on outer surface (5) to engine (3a, 3b). At that, additional air inlet channel (8a, 8b) includes the appropriate additional filter element (9a, 9b) of inlet hole cover; besides, air supply to engine (3a, 3b) in case of interlocking in air inlet hole (2a, 2b) is changed over to additional air inlet channel (8a, 8b, 8') in compliance with control device.
EFFECT: invention ensures minimum engine wear using simple hardware.
