A one-piece barrel assembly cart includes a right assembly cart base connected with a left assembly cart base and at least three stabilizer rings that are attached to the assembly cart base. The one-piece barrel assembly cart may be used to stabilize a tapered cured composite barrel, for example the large fuselage barrel of the aft section of a large new generation aircraft, such as a 7E7 Boeing airplane. A modular assembly cart includes at least two identical modules. Each of these modules includes a cart base and a stabilizer ring. The diameter of the inner surface of the stabilizer ring may vary as needed. Other modules including a fuselage support may be added. By providing modular assembly carts any shape and size of a one-piece composite barrel may be stabilized after curing of the composite material.

We claim: 1. A one-piece barrel assembly cart, comprising: a right assembly cart base having an inner surface; a left assembly cart base having an inner surface, wherein said left assembly cart base is joined with said right assembly cart base at said inner surfaces; at least two stabilizer rings,
We claim: 1. A one-piece barrel assembly cart, comprising: a right assembly cart base having an inner surface; a left assembly cart base having an inner surface, wherein said left assembly cart base is joined with said right assembly cart base at said inner surfaces; at least two stabilizer rings, wherein each stabilizer ring is divided into a right half and a left half, wherein said right half is attached to said right assembly cart base and wherein said left half is attached to said left cart base; a plurality of clamps being attached to said stabilizer rings; a plurality of casters attached to said bottom and evenly distributed along said outer surface and said inner surface of said right assembly cart base and of said left assembly cart base; a plurality of support jack assemblies attached to said bottom and evenly distributed along said outer surface and said inner surface of said right assembly cart base and of said left assembly cart base; a plurality of pitch and yaw jack assemblies attached to said bottom and evenly distributed along said outer surface and said inner surface of said right assembly cart base and of said left assembly cart base; and a plurality of ring support jack assemblies mounted underneath each of said stabilizer rings. 2. A one-piece barrel assembly cart, comprising: a cart base having wheels; at least two stabilizer rings mounted to the cart base, wherein each stabilizer ring is divided into sections but can be joined together to form a continuous ring; and a plurality of barrel clamps attached to said stabilizer rings; wherein said stabilizer rings receive a fuselage barrel made out of a cured composite material having a tapered shape, an outside, and including longitudinal stiffeners, wherein said clamp attaches to said outside of said barrel at a location of said longitudinal stiffener. 3. A one-piece barrel assembly cart, comprising: a cart base having wheels; at least two stabilizer rings mounted to the cart base, wherein each stabilizer ring is divided into sections but can be joined together to form a continuous ring; and a plurality of barrel clamps attached to said stabilizer rings; wherein said cart base, and said stabilizer rings stabilize a composite fuselage barrel having a length of at least 24 feet. 4. A cart for removing a fuselage barrel from an inner mold line (IML) tool, the cart comprising: a cart base having wheels; at least two stabilizer rings attached to the cart base for stabilizing the barrel before the barrel is removed from the IML tool, wherein each stabilizer ring is divided into a right half and a left half configured to be joined to form a continuous ring, each said continuous ring half adapted to rotate relative to said cart base; and a plurality of clamps distributed about the rings and operative on an outer surface of the barrel for preventing the barrel from collapsing while the barrel is being wheeled away from the IML tool. 5. The cart of claim 4, further comprising at least six ring guides attached to the cart base, and wherein said stabilizer rings are movable on said ring guides. 6. The cart of claim 4, wherein said cart base includes right and left assembly cart bases that are joined together, and wherein the right assembly cart base has the same dimensions as the left assembly cart base. 7. The cart of claim 4, wherein the rings fit around a fuselage barrel having a diameter of at least 19 feet. 8. The cart of claim 4, wherein said clamps are attached to inner surfaces of the stabilizer rings. 9. The cart of claim 4, wherein said stabilizer rings receive said fuselage barrel, wherein said clamps attach to said fuselage barrel, and wherein said cart further comprises a plurality of ring support jack assemblies mounted underneath each of said stabilizer rings for rotating said stabilizer rings. 10. The cart of claim 4, wherein said clamps are force limiting vacuum toggle clamps. 11. The cart of claim 4, further comprising means for lifting the cart so the fuselage barrel can be mated with another fuselage barrel. 12. A system comprising: an aircraft fuselage barrel; and the cart of claim 4, wherein the barrel is carried on the cart, stabilized by the rings, and prevented from collapsing under its own weight by the clamps. 13. The system of claim 12, further comprising an additional fuselage barrel and an additional for carrying the additional barrel, the carts positioned so the barrels are mated.
