A composite shell which can be used, in particular, in the manufacture of bodies or compartments of flying vehicles used in rocketry or aeronautics, comprises a load-bearing framework formed of intersecting stiffening ribs, and an outer load-bearing shell. Box-shaped cover plates are secured with glue an the cross nodes of the stiffening ribs from the internal surface of the framework, and thin-walled plates are secured at the outer surface of the shell by threaded rod elements that pass through the shell and framework and are connected to the box-shaped cover plates. In one embodiment, the composite shell is formed of a plurality of panels connected together at their abutting edges. A connection joint between adjacent panels is formed by connecting elements in the form of box-shaped cover plates of a rectangular cross-section that span the connection joint between the panels and are mounted on the interior surfaces of the panels, and plates mounted, on the outer surfaces of the panels spanning the joint and connected to the box-shaped cover plates by threaded rod elements.
