Installing air filters on helicopters is already a kind of advanced technology in itself.
After all, before this, there wasn't any aircraft in the world that would install air filters on their air intake ducts, as it would greatly affect the airflow.
But Chen Xin, leveraging the powerful capability of system upgrades, developed an air filter that can be installed on helicopters, allowing them to fly even with air filters.
"Did installing the air filter affect the aircraft's power performance?" Chen Xin placed two air filters removed from a Z-20 helicopter on the table, disassembling them while asking the pilot next to him.
