AI Technical Summary
Existing oxygen concentration testing equipment is mainly used in the biological and petroleum fields, and lacks the conditions for calibration in flight environments, making it difficult to guarantee the reliability and accuracy of aircraft fuel tank oxygen concentration testing equipment.
The external, internal, and fuel gas environments of the aircraft fuel tank were constructed. A standard oxygen concentration standard environment was formed using a standard gas replacement method. The temperature, pressure, and fuel gas state of the fuel tank under flight conditions were simulated, and the oxygen concentration testing equipment was calibrated.
It enables the calibration of oxygen concentration testing equipment in flight environments, ensuring the reliability and accuracy of the testing equipment under complex conditions and meeting the needs of flight test evaluation of aircraft fuel systems.
