A structure for clustered stator vanes of the type utilized in axial flow gas turbine engines is disclosed. Concepts and techniques for retaining the vanes in position within the engine are developed. The concepts are well suited to structures in which the vanes are metallurgically joined. In one embodiment the stator vanes are grouped in pairs of a first, or principal vane and a second, or secondary vane each. East secondary vane is joined to a complementary principal vane along planes which preclude radial or axial movement of the secondary vane with respect to the principal vane, in the event that the bond between the joined vanes fails.
