Abstract (en)
A method for manufacturing an adaptive stage (10) for a turbine comprises the steps of: - manufacturing a plurality of blades (20), each blade including a pressure side (23) and a suction side (24) extending from a leading edge (25) to a trailing edge (26), - fixing each blade (20) to an inner blade ring (31, 32) and an outer blade ring (41, 42), in order that the leading edge (25) and the trailing edge (26) extend from one to the other of the inner blade ring (31, 32) and the outer blade ring (41, 42), - fixing a first cover ring (51) and a second cover ring (52) between the inner blade ring (31, 32) and the outer blade ring (41, 42), the inner blade ring (31, 32) and the outer blade ring (41, 42) being interposed between the first cover ring (51) and the second cover ring (52).
