Abstract: A liquid storage tank, for example an aircraft fuel tank, having a tank wall enclosing a liquid storage space, and a tie assembly located at least partially within the liquid storage space. The tie assembly includes an elongate member, for example a wire or cable, and a plurality of attachment devices fixed to an inner surface of the tank wall. The elongate member includes a plurality of spaced part points along its length, each of the spaced apart points being fixed to a respective attachment device such that the tie assembly resists outward deformation of the tank wall.

Abstract: Disclosed is a liquid storage system having an outer tank (e.g. an aircraft fuel tank) for containing a liquid (e.g. aircraft fuel), the outer tank enclosing a liquid storage space; an inner tank located within the outer tank and enclosing the liquid storage space; and at least one coupling element associated with the outer tank and the inner tank for maintaining the tanks in a spaced apart relationship; wherein the coupling element(s) is/are deformable such that, on application of a force to the inner tank, at least part of the inner tank moves relative to the outer tank.
