✦ Synopsis

In order to improve the torque performance of the propeller type wind turbine, and to increase the relative rotational speed of the generator, two-staged wind turbines were proposed. The experimental results of a wind tunnel test showed that self-starting characteristics of two-staged co-axial type were improved by attached front wind turbines for two bladed main wind turbine, and the relative rotational speed of counter-rotating type was increased.

Then, a counter-rotating type trial machine was constructed and a wind tunnel test was also conducted. The test result demonstrated the technical possibility of conterrotating type wind powered generator.
