  1. Wind Turbines

  2. Drag-type turbines Persian windmill Chinese wind wheel Saviounus Lift-type turbines VAWT, Vertical Axis Wind Turbine Darrieus HAWT, Horizontal Axis Wind Turbine The Danish concept American multiblade Grumman windstream Different types of wind turbines

  3. Drag-type turbines Savonious The Persian windmill The Chinese wind wheel

  4. Drag-type turbines Ref: www.ifb.uni-stuttgart.de/~doerner/edesignphil.html

  5. Lift-type turbinesVAWT, Darrieus

  6. Lift-type turbinesVAWT, Darrieus

  8. Lift-type turbinesHAWT, American Multiblade

  9. Lift-type turbinesHAWT, Grumman Windstream

  10. The blades upwind the rotor Constant speed on the rotor Power output limitation Stall control Brakes Mechanical Aerodynamic Lift-type turbinesHAWT, The Danish Concept

  11. Development of HAWT HEIGHT [M]

  12. Wind power and energy A • Power output from wind turbines: • Energy production from wind turbines: C

  13. Energy flux for wind turbines Where: P = Power [W] r = Density [kg/m3] c = Velocity [m/s] A = Area [m2] h = Efficiency [ - ] Recommended literature: Wind Turbine Technology, David A. Spera, ISBN no. 0-7918-1205-7

  14. The world’s energy potential for land based wind turbines Estimated energy output in kWh/kW from a wind turbine that are dimensioned for 11 m/s

  15. Global Installed wind power
