Title: BLADE RING FOR AN AXIAL TURBOMACHINE, AND A METHOD FOR ADJUSTING THE MAXIMUM FLOW RATE OF SAID BLADE RING
Abstract:
The invention relates to a blade ring for an axial turbomachine (1), comprising an outer surface (2) that is arranged on an outer ring (24) and faces radially inwards, and an inner surface (3) that is arranged on an inner ring (23) and faces radially outwards, said surfaces being arranged concentrically and parallel to one another and delimiting an annular flow channel (4) that tapers in the main flow direction (17) of the axial turbomachine (1), as well as at least one adjustment blade (7) that is arranged so as to be displaceable, in said flow channel (4), parallel to a surface line (6) of one of the surfaces (2, 3) by means of a guiding device (14, 15), and that is able to be fixed, in a predetermined position, to at least one of the rings (23, 24).
