The following notes are taken from Wind Turbine Technology by Ahmad Hemami.
- Wind Turbine Types
- Horizontal Axis
- HAWT
- must be yawed into the wind for max wind capture, follow wind direction
- most common wind turbine is propeller wind turbine, works based on lift force
- Vertical Axis
- VAWT
- not sensitive to wind direction
- easier accessibility to most of the components
- Darrieus Machine
- weak starting torques
- good power coefficients
- H-Rotor
- weak starting torques
- good power coefficients
- Savonius Rotor
- drag-type turbine can be installed as either VAWT or HAWT
- drag-type turbines have smaller power coefficients
