Abstract (en)
[origin: EP2623717A1] The blade ring has a radially inward facing outer surface and a radially outward facing inner surface, where the outer surface is arranged on an outer ring and the inner surface is arranged on an inner ring. The surfaces are arranged concentrically and parallel to each other and limit an annular flow channel (4) tapering in the main flow direction of the axial turbomachine (1). An adjusting shovel (7) is arranged in parallely displaceable manner to a surface line of one of the surfaces in flow channel by a guide unit. An independent claim is included for a method for adjusting absorption ability of a blade ring.
