VORTEX MACHINE WITH DYNAMIC VORTEX Russian patent published in 2012 - IPC F04D5/00 F04D23/00 F01D1/00 

FIELD: machine building.

SUBSTANCE: machine includes stator and rotor. Working chamber with inlet and outlet channels is formed between them. Width of working chamber cross section is equal to difference between its maximum radius and minimum radius. Blades and divider is located in chamber. They are connected to stator and rotor respectively. Each blade includes front edge. That edge faces rotor. Divider is provided with cutoff edges. Edges are congruent to front edge of blade and restrict the divider surface section facing the front edges of blades. Blade is installed at an angle of 0-26°. Middle line 15 of blade cross section, which is passed through centre of front edge, is formed with straight line inclined towards plane perpendicular to rotor rotation axis at an angle α of 0° to 50°. Blade thickness from its edge to 0.8 of centre elevation of blade front edge increases as per linear law with angle α₁ between generatrixes of outer and inner surfaces of each blade, which are between 5° and 30°.

EFFECT: invention allows improving reliability and efficiency of vortex machine with dynamic vortex.
