Abstract

Die Erfindung betrifft Lauf- und Leiträder (1,2) für Strömungsmaschinen, insbesondere für Verdichter und Ventilatoren, wobei diese zur Verringerung von Strömungsgeräuschen und zur Verbesserung der Kennlinienstabilität zwischen dem Ein- und dem Austrittsquerschnitt für die Strömung aus einer Feststoffmatrix mit einer Vielzahl von Strömungskanälen (21) gebildet werden, in welchen eine Umlenkung der Strömung und die damit verbundene Druckerhöhung erfolgt.
