Abstract

The present invention concerns a wind turbine device having two or more vertical blades as generally used to generate power that gives a self-regulating angular speed using a collective blade-pitch control system with common biasing springs indirectly connected to each of the blades. A multiple retainer struts attachment system is disclosed for each blade to limit the effects of bending stresses on the latter. A new robust blade mounting, construction and design method is also described for use in the present wind turbine device.
