METHOD FOR MEDIUM FLOW ENERGY APPLICATION AND ENERGY-TRANSDUCING DEVICE FOR ITS REALISATION Russian patent published in 2009 - IPC F03D1/06 

FIELD: engines and pumps.

SUBSTANCE: invention is related to methods and facilities for transformation of energy of flows of different physical nature and may be used for transformation of wind or water flows energy. Method is realised by means of flow energy transformation into rotary motion of energy-transducing device, which comprises shaft oriented along medium flow and rotary energy-transducing element fixed in it and arranged in the form of, at least, one blade with fairing having aerodynamic profile symmetrical relative to its transverse plane and installed so that plane of symmetry of its cross section passes through shaft longitudinal axis. Blade is fixed to outlet end of fairing so that one of fairing side surfaces and external surface of blade create single aerodynamic surface, at that blade plane is shifted relative to shaft longitudinal axis. When energy-transducing device is placed in medium flow, pressure of differences is created relative to internal and external surfaces of blades.

EFFECT: pressure increase at internal surfaces of blades and rotation of energy-transducing device with simple design.
