Eurofighter (EFA) wing micro-leak detection using specific IR detection systems.
The inspection of fuel tanks is an obligation prior to the delivery of the aircraft. Currently, leak detection is performed by applying soapy liquid, which generates bubbles indicative of the area where the leak is located. LIR-InfraRed LAB has a procedure for Fuel tank tightness testing using a spectral imaging system for micro-leaks localization.
These systems have been tested on real Eurofighter wing leaks (EFA).
