Abstract
An inner diameter vane shroud for use in a gas turbine engine is comprised of lightweight cast forward and aft shroud components. The forward and aft shroud components are made with an investment casting technique that creates a hollow cavity that runs in a circumferential direction through each component. The forward and aft shroud components are matable to form sockets that receive inner diameter ends of variable stator vanes.
