A Test Method for Testing the Flow of Air Oxygen Supply Equipment

With the development of aviation military and civilian aircraft, the aviation oxygen supply equipment also has higher technical improvements and system innovations. In order to simulate the work of aviation oxygen supply equipment and accurately test the volume flow under high altitude condition, the flow detection method of damping equipment is adopted to detect the flow of oxygen equipment. The gas density correction is not needed during the testing process. The range setting, damper tube structure and other aspects are described, the test principle, identification/calibration methods were studied and verified and the flow test method has been applied for the new test equipment.
