HELICAL TWISTED
VERTICAL AXIS WIND TURBINE (VAWT)
GM300W / GM1K / GM4K


Darrieus VAWTDarrieus roof mounted VAWT

A subtype of the Darrieus turbine with curved blades. This variety has variable pitch blades to reduce the torque pulsation, and is self starting.

FEATURES

  • High starting torque; a wide and relatively flat torque curve.
  • A lower blade speed ratio.
  • Higher coefficient of performance.
  • More efficient operation in turbulent winds
  • A lower blade speed ratio which lowers blade bending stresses
