Abstract

Die Erfindung betrifft einen Vorleitstator (10) für Strömungsmaschinen, insbesondere für Turboverdichter (12), mit mehreren im Anströmbereich eines Verdichterrads (14) angeordneten Eintrittsleitschaufeln (16), deren drallerzeugender Schaufelwinkel in Abhängigkeit eines Fluidvolumenstroms durch die Strömungsmaschine bzw. durch den Turboverdichter (10) verstellbar ist.The invention relates to a Vorleitstator (10) for Turbomachines, in particular for turbocompressors (12), with several in the inflow region of a compressor wheel (14) arranged inlet guide vanes (16) whose swirl-producing blade angle in Dependence of a fluid volume flow through the Turbomachine or through the turbo compressor (10) is adjustable.

Es ist vorgesehen, dass die Eintrittsleitschaufeln (16) sich bei verändernden Strömungsverhältnissen verformen.
