  • Edge stabilizing system and method for composite barrel segments
    Patent number: 10160076
    Abstract: An edge stabilizer for a composite structure includes an elongate edge support segment, defining a geometric shape of an edge of the composite structure, and a connector, configured to attach the edge support segment to the edge of the composite structure. The edge support segment comprises first and second halves configured to attach together around the edge, each half including a shoulder, opposing mating relationship of the shoulders defining a slot for receiving the edge. The edge stabilizer can be part of a system for stabilizing an edge of a composite barrel section. The system can also include a moveable cart, the barrel section being supportable upon the cart.

  • Transport and assembly system and method for composite barrel segments
    Patent number: 9796483
    Abstract: A barrel assembly for a composite structure includes a barrel of composite material, a first end ring, and a mid support. The barrel of composite material has a first end, an interior surface and an outer surface, and the first end ring is removably attached to the first end. The first end ring has a perimeter that is substantially congruent with the first end, and is configured to maintain a shape of the barrel. The mid support is removably disposed within the barrel, and has a plurality of spokes extending outwardly from a central hub to contact the interior surface, to maintain a shape of the barrel.
