Abstract

Fan-Nachleitradschaufelprofile sind in einer neuen, optimalen Ausführung der Skelettlinienwinkelverteilung in einem zwischen einer oberen und einer unteren Begrenzung liegenden Bereich sowie einer der jeweiligen Skelettlinienwinkelverteilung überlagerten spezifischen Dickenverteilung ausgebildet und zeichnen sich gegenüber den bekannten Nachleitradschaufeln durch verringerte Druckverluste und einen erhöhten Arbeitsbereich aus, so dass der Treibstoffverbrauch des Triebwerks gesenkt sowie dessen Betriebsstabilität erhöht werden kann.
