GUIDE VANE FOR TURBOMACHINE, TURBOMACHINE AND METHOD OF ASSEMBLING GUIDE VANE Russian patent published in 2016 - IPC F01D9/02 F01D25/24 

FIELD: machine building.

SUBSTANCE: guide vane of a turbomachine includes inner and outer shells, two blades and an overlapping area. One of said inner and outer shells comprises first openings. Each blade of said guide vane comprises at same first end a mounting pad with second openings located opposite said first openings. Said vanes are connected with one of said inner or outer shells by means of fastening means, entering said first and second openings. Said overlapping area covers said fastening means and comprises upper and lower surfaces. Said upper surface forms an overlapping plane at whose level air is circulated, wherein said overlapping plane has a shape adapted to repeat channel profile. Said lower surface forms a mounting plane having a recess adapted to interact with said fastening means for retaining said overlapping area. Another invention of said group relates to a turbomachine group comprising said guide vane. When assembling said guide vane, said second openings of mounting pads of blades are positioned opposite said first openings. Mounting pads are held at one of said shells by means of fastening means. Spikes of said overlapping area are inserted into grooves of a ring and by means of fastening means are rigidly connected to a shell and said overlying area.

EFFECT: group of inventions reduces weight of turbomachine and simplifies assembly of guide vane thereof.
