Ceramic turbine structures |
摘要 |
An outer ceramic shroud for a gas turbine engine includes a plurality of ceramic ring members each housing a rotating blade row of the turbine and further including ceramic stator vane stages located alternately between each of the ring members and having a radially outer rim portion thereon axially aligned with the ring members. The ring members and rims have tongue and groove means thereon for interconnection thereof into a continuous outer high temperature ceramic shroud maintained in axially assembled relationship by a pressure loaded piston member for applying a load to the shroud components during engine operation as a direct function of the discharge pressure of the engine compressor and a supplemental spring to load the shroud components when the discharge pressure drops, thereby to maintain the operative position of stator vane stages.
