Can air compressors be used in aerospace?

Air compressors are indeed widely used in the aerospace field. The following is its specific application:

ground air supply system for rocket launch: Before the rocket is launched, an air compressor is used to provide a detailed "physical examination" for the rocket ". High-pressure nitrogen purges the entire interior of the rocket through an air compressor to ensure that there are no foreign objects inside the rocket. In addition, the new generation of launch vehicles use low-temperature hydrogen and oxygen fuel. After refueling, the temperature of the internal structure of the rocket will become extremely low. At this time, it is necessary to constantly use a high-pressure oil-free compressor to provide a large flow of dry, pure high-pressure air to blow off the cabin to prevent condensation and water vapor.

Engine simulation pneumatic experiments: In the aerospace field, air compressors are also often used in engine simulation pneumatic experiments to test the performance of the engine under various airflow conditions.

High-altitude bench test system and start-up component test system: Both systems also require air compressors to provide the necessary air pressure environment to simulate operation at high altitude or under specific start-up conditions.

In summary, air compressors play an indispensable role in the aerospace field because they can provide stable and controllable compressed air. From the preparation before the rocket launch to various simulation experiments, it is inseparable from the support of the air compressor.
