A baffle 40 for locating in a tank 16 for containing liquid (e.g. an aircraft fuel tank). The baffle is a tubular member through which liquid may flow, comprising a first tubular portion 42 providing a tubular outer wall, and a second tubular portion 44 providing a tubular inner wall and located within the first tubular portion. The tubular portions are substantially parallel and are spaced apart to define a chamber 46 therebetween. The baffle further comprises radial side walls between the first and second tubular portions 42, 44 such that the chamber 46 is a sealed chamber. The chamber may be filled with a compressible gas or gaseous mixture. A liquid storage tank system containing a plurality of baffles is also disclosed. The baffles may be parallel to each other, substantially fill the tank and have spacers between the baffles and tank walls. The baffle(s) may reduce hydrodynamic ram pressure generated in the liquid by a high velocity foreign body projectile 24 piercing the tank wall. |
