Fuel tank assembly
First Claim
1. A fuel tank assembly comprising:
- a bladder defined between an exterior bladder wall and an interior bladder wall, wherein the interior bladder wall defines a volume for storing fuel, and wherein the exterior bladder wall is comprised of a different material than the interior bladder wall so as to be at least more rigid than the interior bladder wall;
an inlet opening into the bladder defined between the exterior and interior bladder walls in order to permit a pressurized gas to be introduced within the bladder such that the exterior and interior bladder walls are in contact with the pressurized gas; and
a plurality of connectors extending between the exterior and interior bladder walls in order to at least partially limit expansion of the bladder while permitting the pressurized gas to flow past the connectors in order to be housed within the bladder on opposite sides of the connectors.

Abstract
A fuel tank assembly are provided which may limit the damage otherwise occasioned by the impact of a ballistic projectile. The fuel tank assembly may include a bladder defined between exterior and interior bladder walls, with the interior bladder wall defining a volume for storing fuel. The exterior bladder wall is at least as or more rigid than the interior bladder wall. The fuel tank assembly can also include connectors between the exterior and interior bladder walls to at least partially limit expansion of the bladder. The fuel tank assembly can also include an inlet opening into the bladder to permit a pressurized gas to be introduced into the bladder. The fuel tank assembly may also include a valve through the interior bladder wall into the volume for storing fuel to permit at least some of the pressurized gas to be introduced therein.

7. A fuel tank assembly comprising:
-
a rigid fuel tank; an expandable bladder wall disposed within and connected to the fuel tank to thereby define a bladder bounded by the fuel tank and the bladder wall, the bladder wall formed of a different material than the fuel tank and configured to transition from a deflated configuration in which the bladder wall is proximate the fuel tank to an expanded configuration in which the bladder wall is spaced from the fuel tank; an inlet opening into the bladder in order to permit a pressurized gas to be introduced within the bladder such that the fuel tank and the bladder wall are in contact with the pressurized gas; and a plurality of connectors extending between the fuel tank and the bladder wall in order to at least partially limit expansion of the bladder wall while permitting the pressurized gas to flow past the connectors in order to be housed within the bladder on opposite sides of the connectors. - View Dependent Claims (8, 9, 10, 11, 12, 13, 14)
