ROTOR OF TURBINE PLANT, COMPRESSOR AND TURBINE FOR TURBINE PLANT AND METHOD OF ROTOR MODERNISATION Russian patent published in 2015 - IPC F01D5/30 

FIELD: machine building.

SUBSTANCE: rotor of the turbine plant contains the rotor shaft, several adjacent work blades installed one after one, and spacer between the blades. The rotor shaft has a intake groove along the periphery, the blade tails are inserted in this groove. The spacers are installed in the intake groove of the rotor shaft between two adjacent work blades. On the external side of the tail near the work side the work blades have the curved wall contour. The spacers on the external side also have the curved wall contour. The external sides of the blade tails and spacers are radially aflush to each other in the direction along the periphery, and wall contour in the axial plane of the rotor section has the concave bend. Other inventions of the group refer to the compressor and turbine of the turbine plant, which contains the above rotor. During the rotor modernisation of the turbine plant the work blades are replaced by the work blades that have on the external side of the tails near the work side of blades the curved wall contour, and spacers are replaced by spacers also having the curved wall contour on the external side.

EFFECT: simplifying the rotor manufacturing of the turbine plant.
