The present development relates to an improved wing having a tip tank assembly. The tip tank assembly is attached to a distal end of an outer wing section. The tip tank assembly includes a tank, a pair of mounting brackets and a fairing assembly. The fairing assembly includes a nose piece, a central piece, a tail piece, an inner end plate, and an upper close out piece. The inner end plate extends perpendicularly downward from a lower surface of the outer wing section eventually terminating at a bottom portion of the central piece. The inner end plate acts as an air dam to trap high pressure air that is generated during flight, substantially increasing the lift of the wing. Lastly, the upper close out piece extends between an upper wing surface and an upper portion of the central piece increasing the overall wingspan of the aircraft.

The invention claimed is: 1. A wing tip tank assembly for installation on a wing portion of an aircraft at a distal end of the wing portion, including: a forward tip portion, an aft tip portion, and a cylindrical portion with the forward tip portion in the general direction of a forward portion of the aircraft and the aft tip portion in the general direction of an aft portion of the aircraft, wherein an upper surface of the wing tip tank assembly is generally level with an upper surface of the wing portion; an end plate fairing disposed along an exterior, inboard side of the wing tip tank assembly and depending from the lower surface of the wing portion and extend toward a lower surface of the wing tip tank assembly, wherein the end plate fairing includes a generally planar surface adapted to extend from the lower surface of wing portion and generally perpendicular to the lower surface of the wing portion; a closeout fairing adapted to extend from the upper surface of the wing portion toward the upper surface of the wing tip tank assembly; a nose cone extending forward from the forward tip portion of the wing tip tank assembly; and a first tail cone extending aft from the aft tip portion of the wing tip tank assembly. 2. The aircraft set forth in claim 1 wherein the wing tip tank assembly is adapted to retain and supply aircraft fuel to at least one propulsion unit associated with the aircraft. 3. A tip tank assembly mounted to a distal end of a wing of an aircraft, the wing having an upper surface and a lower surface, the aircraft having a longitudinal axis extending from a forward portion to an aft portion, the tip tank assembly comprising: a central piece including a first end, a second end, an inner side portion, and an outer side portion; a nose piece disposed at the first end of the central piece; a tail piece disposed at the second end of the central piece; and an inner end plate piece extending perpendicularly downward from the lower surface of the wing and adjacent the exterior of the inner side portion of the central piece and inboard facing; wherein the nose piece, the tail piece, the inner end plate piece, and the outer side portion of the central piece form an aerodynamic surface and the inner end plate piece forms a fairing surface. 4. The tip tank assembly set forth in claim 3, wherein the inner end plate piece extends generally linearly from a forward portion of the wing to an aft portion of the wing. 5. The tip tank assembly set forth in claim 3, wherein the tank for carrying fuel is disposed within a volumetric space defined by the aerodynamic surface. 6. The tip tank assembly set forth in claim 3, further including an upper closeout piece disposed between and adjacent the upper surface of the wing and an upper portion of the central piece. 7. The tip tank assembly set forth in claim 6, wherein the upper closeout piece and an upper portion of the central piece are curved in the same direction as the upper surface of the wing. 8. The tank tip assembly set forth in claim 3, further including a flat tapered tail piece disposed on the tail piece. 9. The tip tank assembly set forth in claim 8, wherein the flat tapered tail piece includes a flat inner vertical surface lying in a vertical plane of the inner end plate piece and abutting a rear portion of the inner end plate piece. 10. The tip tank assembly set forth in claim 3, wherein a cross section along a horizontal plane of the aerodynamic surface is non-symmetrical about its longitudinal axis. 11. The tip tank assembly set forth in claim 10, wherein the cross section of the aerodynamic surface includes a curved outer side portion.
