The invention discloses a submerged air inlet of an aircraft based on diverter air introduction. The submerged air inlet of the aircraft based on the diverter air introduction comprises a diverter, an ejector nozzle, an aircraft body using the air inlet, an air inlet passage and an engine, wherein according to the submerged air inlet, the diverter is arranged on the surface of the aircraft body in front of an air inlet port of the air inlet passage; and the ejector nozzle is mounted in a stern room of the aircraft body. Under a pumping effect of the ejector nozzle, outside airflow, in particular low-energy airflow close to a boundary layer of the aircraft body, flows into the diverter from a diverter inlet; under guiding constraint conditions of a diverter flow guiding surface and a diverter side surface, the outside airflow flows out of a diverter outlet and enters the interior of the aircraft body; low-energy flow of the boundary layer on the surface of the aircraft is absorbed into the stern room of the aircraft body before entering the air inlet passage; and the low-energy flow of the boundary layer, which is absorbed into the stern room of the aircraft body, is ejected and exhausted into the atmospheric environment. The submerged air inlet of the aircraft based on the diverter air introduction, disclosed by the invention, is advantaged in that the low-energy flow of the boundary layer is effectively eliminated, the total pressure recovery coefficient of the air inlet passage is increased, the flow field distortion factor of the submerged air inlet is reduced and the submerged air inlet has good engineering application value.
