SYSTEM OF AIR EXHAUST JET DEFLECTORS OF HEAT EXCHANGER Russian patent published in 2023 - IPC B64D33/04 B64C1/38 F01N13/14 

FIELD: aviation.

SUBSTANCE: invention relates to air exchange systems on board an aircraft. The heat exchanger air ejection jet deflector system comprises a deflector, a high-temperature exhaust channel opening of the auxiliary power unit, a high-temperature heat exchanger exhaust channel opening and a low-temperature heat exchanger exhaust channel opening, located sequentially against the flight direction on the tail boom of the aircraft. In the channel of the high-temperature heat exchanger in front of the high-temperature heat exchanger, at least one branch of the additional adjacent channel is made with the air jet output to the surface of the aircraft from the side in the direction of flight adjacent to the opening of the channel of the high-temperature heat exchanger.

EFFECT: eliminating high-temperature effects on the outer surface of an aircraft with reduced radar visibility while reducing the mass of the structure and ensuring efficient operation of the heat exchanger in all flight modes.
