Abstract
Protective insert plates () installed on a working gas face () of a turbine vane platform () provide replaceable portions of a turbine shroud for improved maintenance. The plates act as tiles, and may be formed of ceramic materials for thermal protection. Two cages () in the vane platform slidably receive the two insert plates () from opposite circumferential sides () of the platform. The plates slide into the cages up to the pressure and suction sides () of the vane airfoil (). The plates may have proximal edges () shaped to fit the respective pressure and suction sides of the vane airfoil. A retainer platemay be attached to a flange () on the cooled face () of each platform, and may contact each insert plate with a locking device () to prevent sliding of the plate in the cage.
