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.

Static vane assembly for an axial flow turbine

A blade of a turbomachine, especially of a steam turbine, is characterized in that the chord length (s) in the middle region of the blade airfoil is shorter than the chord lengths (s, S) in the tip-side region or root-side region of the blade airfoil. As a result of this, a distribution of a Zweifel parameter over the longitudinal extent of the blade airfoil is achieved which minimizes the losses of a blade cascade of the blades.

Turbomachine blade with variable chord length

The blades of a turbomachine comprise airfoils, which are bent such that the lean angle (&#x3c6;), defined as the angle which the stacking line of the airfoil includes with the radial direction, and measured in the direction of rotation (&#x3c9;), is variable along the width of the flow channel and decreases from the hub towards the housing.
