A test rig that reproduces high temperature and high pressure conditions found in a gas turbine engine for testing materials under these conditions. The test rig includes a combustor surrounded by an upper plenum chamber and an exhaust plenum that receives a hot gas stream from the combustor. A transparent channeling vessel guides the hot gas stream from the combustor over a test specimen on which a material to be tested is mounted. The hot gas stream exits the clear channeling vessel and into the exhaust plenum where the stream is cooled by diluting the stream with cooling air. A viewing portal is located in the exhaust plenum so that the material can be observed through the clear vessel.

A stator assembly having an inner shroud and an outer shroud with a plurality of airfoils extending between the shrouds, and a vibration damping horn extending from one of the shrouds and aligned with the airfoil, the vibration damping horn having a higher stiffness than the airfoil, and where the vibration damping horn vibrates against a damping spring or within a viscous fluid to dampen the vibration of the stator assembly. The vibration damping horns are thicker than the airfoils to provide for the higher stiffness. The damping spring is enclosed between the shroud and seal to support the spring.
