IMPELLER turbomachinery with a guy SHOULDER

摘要

Application area; The gas turbine technology, in particular the design of turbomachinery.; SUMMARY OF THE iNVENTION; Impeller turbomachine comprising a pair of vanes with shroud shelves mounted in grooves disk their sided shank, which on one hand have a substantially flat surface placed in contact with each other and bandage shelves each vane pair are made with displacement against each other with respect to plane its blade shank by an amount which is determined by the equation:; a = (0,0001-0,002) H,; and wherein - said counter offset value headband shelves paired blades;; H - width shroud flange of the rotor blade in a plane normal to the contact end surface.; Technical results; Increase the damping characteristics of the impeller blades of the turbomachine and a reduction of static loads in the plume through the effective use of simultaneous interaction between them as the flat surfaces of the shanks of the blades generally paired groove and shroud flanges blades pairs.
