Claim 0:
1. An airfoil assembly comprising:
first and second fiber-reinforced composite airfoil rings each comprised of inner and outer platform sections, a suction side wall extending between the inner and outer platforms, and a pressure side wall extending between the inner and outer platforms, each of the first and second fiber-reinforced composite airfoil rings including an endless braid, the first fiber-reinforced composite airfoil ring mating at an interface with the second fiber-reinforced composite airfoil ring such that the suction side wall of the first fiber-reinforced composite airfoil ring and the pressure side wall of the second fiber-reinforced composite airfoil ring together form an airfoil that circumscribes an internal cavity, wherein the interface along the airfoil includes a gap configured to emit cooling air from the internal cavity, and the gap diverges starting from an inner surface of the internal cavity and continuing to an outer surface of the exterior of the airfoil, the suction side wall including a first gusset projecting into the internal cavity and the pressure side wall including a second gusset projecting into the internal cavity, the first gusset and the second gusset defining a passage there between, and a seal including an aft seal wall including inlet orifices, a forward seal wall including outlet orifices, and radially inner and outer end walls joining the forward seal wall and the aft seal wall to form a seal ring that circumscribes a seal manifold region that connects the inlet orifices and the outlet orifices to provide a flow-through passage through the seal, the forward seal wall and the aft seal wall defining a first pair of legs straddling the first gusset and a second pair of legs straddling the second gusset.
