Abstract:
Systems and methods for a segmented aircraft refueling tube with a tube interface include a plurality of seals configured to deform while allowing relative movement between tube segments. The systems include a tube interface that includes a first ring, a second ring, a first seal disposed between a first ferrule and the first ring, a second seal disposed between a second ferrule and the second ring, a third seal disposed between the first ring and a sleeve, and a fourth seal disposed between the second ring and the sleeve. The plurality of seals per ring allow for misalignment between the ferrules to be accommodated by two or more seals.
