Abstract

Die Erfindung betrifft ein Spaltkontrollsystem zum Einstellen eines Laufspalts (L) zwischen einem Rotorschaufeln (10) umfassenden Rotor (12) einer Strömungsmaschine (14), insbesondere einer Gasturbine, und einer diesen zumindest abschnittsweise umgebenden, wenigstens zwei Segmente (16a-d) umfassenden Ummantelung (18), mit wenigstens einer Verstelleinrichtung (20), welche mit wenigstens einem Segment (16a-d) der Ummantelung (18) koppelbar ist und mittels welcher das wenigstens eine Segment (16a-d) zum Einstellen des Laufspalts (L) radial bezüglich einer Drehachse (D) des Rotors (12) bewegbar ist, wobei jedes Segment (16a-d) der Ummantelung (18) mit wenigstens drei Verstelleinrichtungen (20) des Spaltkontrollsystems gekoppelt ist. Die Erfindung betrifft weiterhin eine Strömungsmaschine (14), insbesondere eine Gasturbine, sowie ein Verfahren zum Einstellen eines Laufspalts (L).
