The invention discloses a deployable, inflatable conformable fuel tank assembly constructed to be installed at a certain location on an aircraft and to be retained at that certain location throughout the entire flight operation of the aircraft. The fuel tank assembly is constructed to be movable between a first, deployed aerodynamic configuration in which the assembly can hold a supply of liquid fuel, and a second, stowed aerodynamic configuration in which the exterior surface of the assembly conforms to a surface of the aircraft underlying the assembly. The fuel tank assembly is fabricated from flexible and foldable fiber-reinforced membrane material and includes a first, inner, liquid chamber for containing a supply of liquid fuel and a second, outer, gas chamber which at least partially envelopes the liquid chamber and which is constructed to contain a pressurized volume of gas sufficient to maintain the fuel tank assembly in the first, aerodynamic deployed configuration irrespective of the quantity of fuel in said first, inner, liquid chamber. Upon depletion of the fuel in the inner, liquid chamber, the pressurized gas in the outer, gas chamber can be evacuated in order to cause the fuel tank assembly to move into the stowed aerodynamic configuration.

[ What is claimed is:] [1.] A method of conforming a fuel tank assembly with two different aerodynamic configurations on an aircraft, said method comprising:constructing the assembly with a first, inner, liquid chamber for containing a supply of liquid fuel in a first, aerodynamic deployed configuration of the assembly;constructing the assembly with a second, outer, gas chamber for containing a pressurized volume of gas in the first, aerodynamic deployed configuration of the assembly;incorporating bidirectionally extending structural elements in said second, outer, gas chamber which are effective to hold the assembly in said first, aerodynamic deployed configuration under the force of the pressurized gas irrespective of the quantity of liquid fuel in the first, inner liquid chamber;forming the structural elements of a foldable material so that the assembly can be conformed to a second, aerodynamic stowed configuration in which the exterior surface of the assembly conforms to a surface of the aircraft underlying the assembly;installing the fuel tank assembly at a certain location on an aircraft;retaining the fuel tank assembly at said certain location throughout the entire flight of the aircraft;admitting pressurized gas to and retaining pressurized gas in the second, outer, gas chamber to conform the assembly to and to retain the assembly in said first aerodynamic deployed configuration when the first, inner liquid fuel chamber contains a supply of liquid fuel; andevacuating the pressurized gas from the second, outer, gas chamber to conform the assembly to the second, aerodynamic stowed configuration when the supply of fuel in the first, inner, liquid chamber has been depleted. [2.] A conformable fuel tank assembly constructed to be installed at a certain location on an aircraft and to be retained at that certain location throughout the entire flight operation of the aircraft, said assembly comprising:a first, aerodynamic deployed configuration in which the assembly can hold a supply of liquid fuel;a second, aerodynamic stowed configuration in which the exterior surface of the assembly conforms to a surface of the aircraft underlying the assembly; anddeployment means for deploying the conformable fuel tank assembly between said first aerodynamic deployed configuration, and the second, aerodynamic stowed configuration; andwherein said deployment means comprises:first, inner, liquid chamber means for containing a supply of liquid fuel; andsecond, outer, gas chamber means which at least partially envelope said liquid chamber means and which are constructed to contain a pressurized volume of gas sufficient to maintain the fuel tank assembly in said first, aerodynamic deployed position irrespective of the quantity of fuel in said first, inner, liquid chamber means.
