COMPRESSOR VANE, METHOD OF PRODUCTION AND COMPRESSOR VANE APPLICATION Russian patent published in 2009 - IPC F04D29/38 

FIELD: motors and pumps.

SUBSTANCE: invention relates to the compressor (9) vanes (50), which are provided with tailpiece (55), platform (59) and adjoining vane profile (61) with profile end along the main axis. The vane profile (61) is made up with convex wall (69) from the suction side and perpendicular to the wall (69) from the side of concave wall (67) at pressure side. With regard to flow medium, the above surfaces stretch from inlet edge (63) to outlet edge (65) and middle line (71) of profile is in-between. The end surface (73) stretches crosswise with regard to the main axis (53) on the end (72) of profile. Packing bevel (75) is available, at least, partially, on the end surface from the inlet edge (63) to outlet edge (65). The vane profile (61) is also available on the end surface, including packing bevel (74). The vane profile (61) has vane profile height (H), which goes along the main axis (53) direction. In order to produce efficient and improved from aerodynamics point of view compressor vane with the modified packing bevel with unchangeable packing action, it is proposed to reduce packing bevel (74) height (HL) by 2% from the vane profile (61) height (H).

EFFECT: efficient and improved from aerodynamics point of view compressor vane.
