Hello everyone,
I would ask you what is the advantage of groove applying to upper and lower flanges of spar/rib structures that form fuel boundary of wings. As far as I see, Eurofighter, F-16 and F-35 fighter jets have this groove to inject sealant without removing upper/lower skin. Is there any more requirement for it, such as preventing fuel leakage, blocking seperation of sealant? Or could it be designed the wing without groove channel?
