MOVING BLADE OF THE TURBOMACHINE (OPTIONS) Russian patent published in 2018 - IPC F01D5/30 F04D29/32 

FIELD: machine building.

SUBSTANCE: moving blade of the turbomachine is designed with the possibility for it to be attached to the rotor wheel of one stage of the turbomachine and it has at least one characteristics, which includes at least one of the following items: the width of the journal, the length of the platform, the angle between the bend point of the mentioned platform between and the edge of the platform or the mentioned journal, height of the platform, height of the shank, the shank width and the circumferential width of the mounting base of the moving blade. Moving blade is configured in such a way that at least one mentioned characteristics is matched to the conjugate characteristics of the mentioned rotor wheel, which comprises at least one of the following items: the width of the groove opening, the depth of the hole for the platform, the width of the narrowed part of the groove, the convergence angle of the groove, the depth of the widened part of the groove and the width of the groove dilation. In this case, the specified moving blade has the aerodynamic part of the predetermined profile, which is designed essentially in accordance with the values of X, Y and Z of the Cartesian coordinate system, which are presented in the scaled table that is selected from the group consisting of Tables 1-11, in which the indicated values of X, Y and Z are dimensionless values, which are given with possibility for their conversion into the dimensional distances by means of multiplying these values of X, Y and Z by the certain number, and the X and Y coordinates are the coordinates that, when connected by the continuous arcs, define the profile sections of the aerodynamic part at each height Z, the profile sections of the aerodynamic part at each height Z are connected to each other with the formation of the complete shape of the aerodynamic part.

EFFECT: possibility of undesirable connection of the mentioned moving blade with the rotor wheel of the other stage of the turbomachine is eliminated.
