A gas turbine engine includes a body and a turbine-vane ring coupled to the body. The turbine-vane ring includes a plurality of turbine-vane assemblies. Each turbine-vane assembly includes a vane unit and a heat shield configured to reduce heat transfer to the vane unit from hot exhaust gases during operation of the gas turbine engine.
