A steam turbine with a resonance chamber in the outer annulus opposite a rotating blade row. The resonance chamber provides passive resonance to place the excitation at a frequency away from the natural frequency of the blades.

Steam turbine with resonance chamber

An axial flow turbine is described having a casing defining a flow path for a working fluid therein, a rotor co-axial to the casing, a plurality of stages, each including a stationary row of vanes circumferentially mounted on the casing a rotating row blades, circumferentially mounted on the rotor, with within a stage n vanes have an extension such that at least a part of the trailing edge of each of the n vanes reaches into the annular space defined by the trailing edges of the remaining N-n vanes and the leading edges of rotating blades of the same stage.
