STRUTTURA DI SUPPORTO PER ANELLO PROTETTIVO DI TURBINA DI MOTORE A TURBINA GAS

In order to minimise load transfer between the shroud ring (26) and the turbine casing (13) the shroud ring (26) is radially supported by and radially spaced apart from the turbine casing (13) by an annular brush seal of upstanding filaments 33, 34 of, for example, a nickel based alloy. The groups o...

Zusammenfassung:	In order to minimise load transfer between the shroud ring (26) and the turbine casing (13) the shroud ring (26) is radially supported by and radially spaced apart from the turbine casing (13) by an annular brush seal of upstanding filaments 33, 34 of, for example, a nickel based alloy. The groups of filaments may be oppositely inclined with respect to the shroud ring radii so as to prevent ring rotation. The ring 26 may be of silicon nitride and may be surrounded by a layer of ceramic block 37 to protect the filaments from heat damage.
