How a wet-wing fuel tank on a plane works

1.22K views

I’ve read online on how airliners store their fuel in the wings of the plane, and especially how it’s not in a tank, but its just inside the wings.

How exactly does this work? Does this mean the wings have to be completely air tight? If the inside of the wings are mostly structural elements, how do they deliver the fuel while making sure that there aren’t areas in the wing structure where the fuel gets trapped?

Yeah that would be ideal. One empty and one full would drastically alter the flight characteristics. I don’t know how bad.
