Abstract:
A one-piece barrel assembly cart (10) includes a right assembly cart base (210) connected with a left assembly cart base (220) and at least three stabilizer rings (17, 18, 19) that are attached to the assembly cart base. The one-piece barrel assembly cart may be used to stabilize a tapered cured composite barrel (31), 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 (40) includes at least two identical modules (41). Each of these modules includes a cart base (42) and a stabilizer ring (43). 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.

Abstract:
A rotating internal support (10) for a large hollow structure (18) can include a rigid central truss (12) and two or more annular disks (14) coupled to the truss by support arms (16). The annular disks (14) can be axially spaced along the longitudinal centerlme of the truss (12), and can be coupled to the support arms (16) by guide rollers (20) that allow the annular disks (14) to rotate about a central axis. The internal support (10) can also include support rods (80) with contact pads (82) that extend axially around the annular disks (14) to contact and support the inner surface of the large hollow structure (18) .
