UNIT TO CONVERT MEDIUM FLOW POWER Russian patent published in 2010 - IPC F03D1/02 F03B13/10 

FIELD: engines and pumps.

SUBSTANCE: invention relates to wind and water power engineering, particularly to medium flow power converters that serve to convert flow power into electric power. Proposed unit comprises tube 1 accommodating first turbine with first electric generator and second turbine with second electric generator, first and second devices to center circular first rotor 2 and circular second rotor 5. Note here that circular first rotor 2 with first turbine and second electric generator with second turbine represent an integrated rotary unit wherein inner parts 8 of blades 9.1-9.N of first turbine are attached to second stator 7 of second electric generator. Outer parts 10 of blades 9.1-9.N of first turbine are attached to circular first rotor 2 of first electric generator.

EFFECT: higher efficiency of low power utilisation at particularly low medium flow rates.
