RADIAL-SWIRL TURBO-MACHINE Russian patent published in 2015 - IPC F04D29/28 F04D29/22 

FIELD: machine building.

SUBSTANCE: turbo-machine contains spiral casing, installed in it impeller, carrying and covering disks located between them bend backwards shaped shoulder blades (5). Each blade (5) is equipped with the flap (8) installed with converging clearance (6) in relation to its work surface (7), the flap has concave work and convex end surfaces (9, 10), and have vortex chamber (11) connected tangentially with clearance (6), output converging channels (12) on its surface (10) from chamber (11), and output converging channels (13) with tangential input in it from surface (9) of the flap (8). In the spiral casing on the carrying disk in the vortex chamber (11) of each flap (8) the tangential input converging channel (14) is made, and on the coverage disk from the vortex chamber (11) a tangential output converging channel (15) is made.

EFFECT: increased aerodynamic loading of the radial vortex turbo-machine due to increased kinetic energy of the flow rotation in the vortex chamber by means of creation of the high energy vortex core, and as result the increased pressure difference between the work and rear surfaces of the blades.
