Abstract
A gas turbine CMC shroud plate (A) with a vane-receiving opening () that matches a cross-section profile of a turbine vane airfoil (). The shroud plate (A) has first and second curved circumferential sides (A,A) that generally follow the curves of respective first and second curved sides () of the vane-receiving opening. Walls (A,A,A,A,) extend perpendicularly from the shroud plate forming a cross-bracing structure for the shroud plate. A vane () may be attached to the shroud plate by pins () or by hoop-tension rings () that clamp tabs () of the shroud plate against bosses () of the vane. A circular array () of shroud plates (A) may be assembled to form a vane shroud ring in which adjacent shroud plates are separated by compressible ceramic seals ().
