How often is the air inlet cleaned?

1, often open (for example, the monthly mileage exceeds 2000 kilometers), and the air quality in the local city is poor, so it should be cleaned once every three months.

2. If it is not opened frequently, it can be cleaned once every 1 year or 1 year and a half.

Extended data

Inlet and passage of air required by air jet engine. The intake port not only provides a certain amount of air for the engine, but also ensures the normal operation of the compressor and combustion chamber. The inlet velocity Mach number of turbojet compressor is about 0.4, which strictly limits the non-uniformity of flow field.

In flight, the inlet should realize the deceleration and pressurization of high-speed airflow and convert the kinetic energy of airflow into pressure energy. With the increase of flight speed, the pressurization function of inlet becomes more and more important, which can greatly exceed that of compressor in supersonic flight, so the inlet of supersonic aircraft plays an important role in improving flight performance.

At present, the types of inlet are subsonic inlet, supersonic inlet and adjustable inlet.
