AIR ENGINE Russian patent published in 2008 - IPC F03D7/06 

FIELD: engines and pumps.

SUBSTANCE: air engine with a vertical rotation axis incorporates the blades arranged vertically and closed by end face disks making the channels representing an impulse-reaction turbine. The said turbine intake channels are formed by rigid concave-convex wing-type surfaces, the outlet surfaces making nozzle air flow creating a reactive force. The interblade channel geometry is adjusted by varying the active part blade angle and reducing the reactive channel sizes by pulling the channel elastic walls into the active part hollow spaces by means of a centrifugal regulator. To this end, a wind vane is also used setting the guiding device running on and about a fixed mast opposite to air flow to correct the direction of the said flow coming into the air engine intake channels.

EFFECT: higher efficiency of air flow energy conversion.
