ABSTRACT:
An expandable fuel storage tank for aircraft has a resilient exterior wall panel in the form of a leaf spring anchored at both ends to a surface region of the aircraft, one anchorage being in the form of a simple hinge and the other incorporating a translatory device so that when the wall panel becomes bowed outwards due to the fuel storage tank being filled with fuel the ends of the panel can move relatively toward one another. The panel is formed as a spring such that when fuel is removed from the fuel storage tank, the panel tends to flatten to resume a position in general continuity with the surface region of the aircraft.
