The utility model belongs to the technical field of aero-engine, concretely relates to an air
inlet channel structure matched with
turbojet engine inlet, at least includes air
inlet channel inner tube and air
inlet channel lip, air inlet channel lip is connected in the air inlet port of air inlet channel inner tube, air inlet channel lip and air inlet channel inner tube outside wall lower part have the air inlet channel of intercommunication, the utility model air inlet channel and the air inlet ring reliable
butt joint of engine, and use the positioning pin to carry out the
assembly limit of engine, not only can guarantee the
assembly precision, and will not happen because the air inlet channel and the air inlet mouth of engine seal not strict lead to the problem of air leakage, air leakage, the utility model air inlet channel increases the
cooling channel for engine cabin from the structure design, makes the
airflow can enter the engine cabin from the
cooling channel, effectively cools the engine, improves the service life of engine cabin
rudder machine and other equipment, the utility model reliable air inlet channel structure, help to improve the reliability and stability of whole unmanned aerial vehicle
system.
