Abstract: A gas turbine engine (10) incorporates a particle trap (46) that forms an entrapment region (73) in a plenum (24) which extends from within the combustor (18) to the inlet (32) of a radial-inflow turbine (52, 54). The engine (10) is thereby adapted to entrap particles that originate downstream from the compressor (14) and are otherwise propelled by combustion gas (22) into the turbine (52, 54). Carbonaceous particles that are dislodged from the inner wall (50) of the combustor (18) are incinerated within the entrapment region (73) during operation of the engine (10).

Abstract: A high temperature ceramic/metallic turbine engine (10) includes a metallic housing (12) which journals a rotor member (20) of the turbine engine. A ceramic disk-like shroud portion (46) of the engine (10) is supported on the metallic housing portion (54) and maintains a close running clearance with the rotor member (20). A ceramic spacer assembly (52) maintains the close running clearance of the shroud portion (46) and rotor member (20) despite differential thermal movements between the shroud portion (46) and metallic housing portion (54).

Abstract: A high temperature turbine engine (10) includes a rotor portion (20) having axially stacked adjacent ceramic rotor parts (66, 68, 70). A ceramic/ceramic joint structure (62) transmits torque between the rotor parts (66, 68, 70) through ceramic pins (90) while maintaining coaxial alignment and axially spaced mutually parallel relation thereof despite thermal and centrifugal cycling.
