Abstract

Demper- og tetningsanordning for turbinblad omfattende en tetning og en demper som begge grenser mot ei radialt ytterste flate hvor det ikke er noen gassvei. Tetningen er laget av et plastisk deformerbart materiale og er irmfelt i en utsparing i demperen. Demperen er laget av et stivt materiale som absorberer vibrasjonsenergi som bhr darmet under drift. Utsparingen i demperen muliggjør at både demperen og tetningen kan være posisjonert ved den radialt ytterste flata hvor det ikke er noen gassvei.
