COMPRESSOR BLADE, WHICH HAS AERODYNAMIC PRESET PROFILE PART, COMPRESSOR BLADE, WHICH HAS AERODYNAMIC PART WITH THE SIDE OF LOW-PRESSURE PRESET PROFILE AND COMPRESSOR Russian patent published in 2017 - IPC F04D29/56 F01D5/14 

FIELD: machine engineering.

SUBSTANCE: compressor contains rotating stator blades. Compressor blade has an aerodynamic part of the given profile substantially in accordance with the values of X, Y and Z Cartesian coordinate system, presented in a scalable table, selected from the group of tables consisting of Tables 1-2, in which the X, Y, and Z Cartesian coordinate system are dimensionless values given to convert into the distance by multiplying the dimensional values X, Y, and Z Cartesian coordinate system into a number. Thus, X and Y represent coordinates of which, being connected by continuous arcs, define the aerodynamic portion of the profile section at each height Z. Sections aerodynamic profile portion are joined together at each height Z to form a complete aerodynamic profile part.

EFFECT: increased compressor's efficiency.
