Patent ID: 8919376

Claim:
An aircraft fuel system adapted to mitigate hydrodynamic ram, the system comprising: a fluidly sealed chamber adapted to receive aircraft fuel; and a core composed of a weaved porous material and disposed within the chamber, the core being configured to extend a partial length of a height of the chamber such that a ullage space is created within chamber, the core having: a plurality of columns extending through the core, the plurality of columns being configured to channel a portion of a vapor bubble to ullage space disposed within the chamber, the ullage space being in fluid communication with each of the plurality of columns, the plurality of columns having a wall thickness; and a plurality of orifices extending through the thickness of the plurality of columns, the plurality of orifices providing fuel passage through the thickness of the plurality of columns, the plurality of orifices being configured to localized pressure buildup, which in turn causes the vapor bubble to return to a fluid state prematurely; wherein the vapor bubble from a foreign object entering the core is channeled to both the ullage space and through the plurality of orifices.
