The application of air compressors in aircraft is very extensive, playing a critical role in various systems. Below are some of its application areas:

1.Air Conditioning System: The aircraft's air conditioning system requires a compressor to provide compressed air, which controls the temperature, humidity, and pressure within the cabin, ensuring the comfort of passengers and crew. For instance, the air cycle machine is the power unit of the aircraft's air conditioning system. It utilizes either a cabin pressurizer driven by the engine or high-temperature, high-pressure air directly from the engine, passing through heat exchangers and a turbine expander to cool the air, achieving the effect of refrigeration.

2.Engine Start: Before a plane takes off, an air compressor is used to compress air to start the engine

3.Air Dynamics Testing: In the aerospace field, blowers are used for air dynamics testing, providing high-pressure gas to simulate flight environments and conditions.

4.Oxygen Supply: During high-altitude flight, the cabin's air is thin. Compressed air generated by the air compressor can be treated and supplied to provide sufficient oxygen to the cabin.

5.Pressure Regulation: The pressure and flow of compressed air in the aircraft's cabin can vary significantly at different altitudes and flight conditions. The air compressor adjusts the pressure and flow of the compressed air to maintain an appropriate atmospheric environment in the cabin.

6.Drive Other Devices: Compressed air is also used to drive other devices on an aircraft, such as hydraulic systems and air brake systems.

7.Air Filtration: Air compressors typically come equipped with filtration devices that filter out harmful substances and odors from the air entering the cabin, ensuring the air quality inside the cabin.

8.Aviation Maintenance: At the aviation maintenance base, the compressed air provided by the air compressor is used for major overhaul and inspection hangars, as well as paint hangars. There are very high requirements for the stability and quality of the compressed air.

These applications demonstrate the versatility and importance of air compressors in aircraft design, testing, operation, and maintenance. As technology advances, the performance and efficiency of air compressors are continuously improved to meet the growing demands of the aerospace industry.
