Abstract

Die Erfindung bezieht sich auf einen Strömungsarbeitsmaschinenverstell-Stator mit einer Profilskelettlinie, welche sich längs einer Meridianstromlinie erstreckt, wobei der Stator in radialer Richtung in mindestens drei Zonen (Z0, Z1, Z2) unterteilt ist und wobei die jeweils radial innere und die radial äußere Profilskelettlinie jeder Zone (Z0, Z1, Z2) so ausgebildet ist, dass diese folgenden Gleichungen genügen: α * = α 1 - α P α 1 - α 2
Figure imga0001
 S * S P S
Figure imga0002
wobei
- P ein beliebiger Punkt der Profilskelettlinie,
- α1 der Neigungswinkel an der Stator-Vorderkante,
- α2 der Neigungswinkel an der Stator-Hinterkante,
- α* der dimensionslose, bezogene Winkel der Gesamtwölbung,
- S* die dimensionslose, bezogene Lauflänge,
- αP der Winkel der Tangente an einem beliebigen Punkt P der Profilskelettlinie zur mittleren Meridianstromlinie,
- sP die Lauflänge der Profilskelettlinie an einem beliebigen Punkt P, und
- S die Gesamtlauflänge der Profilskelettlinie sind.
