TURBOMACHINE BLADE, TURBOMACHINE BLADE ASSEMBLY, FAN ROTOR AND TURBOMACHINE Russian patent published in 2019 - IPC F01D5/14 F01D5/30 F04D29/38 

FIELD: machine building.

SUBSTANCE: invention relates to a turbomachine blade. Blade comprises a stylus, a shank engaged with the groove of the turbomachine disc, and an inner flange located in the radial direction between the shank and the blade. Upstream end of shank end is connected to radial inner end of inlet edge of blade by means of upstream edge of connecting section located in radial direction between shank and inner flange, so that radially inner end of the inlet edge of the blade is located further downstream the upstream end of the shank, and/or the downstream end of the shank is connected to the radially inner end of the output edge of the blade by a downstream edge of the connecting portion so that the radial inner end of the blade output edge is located further upstream than the downstream end of the shank. Invention also relates to a turbomachine vane assembly, a fan rotor for a turbomachine, as well as a turbomachine.

EFFECT: invention provides distribution of stresses under normal mode of operation of turbomachine with reduction of local stresses due to increased length of blade root in axial direction.
