Abstract

En stator for det andre trinn i en lavtrykksturbin som har en serie av blader (1) som hvert er definert av koordinater for en diskret kombinasjon av punkter, i et kartesisk referansesystem (X, Y, Z), hvor aksen (Z) er en radial akse som krysser den sentrale akse av turbinen. Profilen av hvert blad (1) er identifisert ved hjelp av en serie av lukkede kryssende kurver (20) mellom selve profilen og planene (X, Y) som ligger med avstander (Z) fra den sentrale akse. Hvert blad (1) har en gjennomsnittlig halsvinkel definert av kosinusbuen av forholdet mellom den gjennomsnittlige halslengde ved den midtre høyde av bladet og omkretshelningen evaluert ved radiusen for det gjennomsnittlige halspunkt, kjennetegnet ved at den gjennomsnittlige halsvinkel er fra 57,8° til 60,8°.
