Leak detection technology of aircraft wing integral fuel tank based on helium mass spectrometer leak detector

The sealing of wing integral fuel tank is the key in the manufacturing technology of wing box, and its sealing performance directly affects the service and safety of aircraft. The integral fuel tank of the wing has large volume and high sealing requirements. The traditional leak detection methods use air tight test and oil tight test. These methods have the disadvantages of low accuracy, high cost, difficult quantification, and low efficiency. In addition, the oil tight test requires a large amount of aviation kerosene to be inject...
