  • An energy source well known since 3000 years
  • Wind availability for operation up to 90% Up to 3 x more efficient than common windmills* Grid independent, scalable and suitable (for almost any territory) Operational costs comparable to fossil fuels* The main facts 3 3 *Source: Fraunhofer Institut IWES, Bremerhaven

  • First flight with energy production Juli 11th 2012
  • Wind power plants uses the same force which are necessary for airplanes Lifting force! For example: Wind turbine with 6 MW capacity rating and a disc of 18.600 m, a capacity factor of 10-40% and an energy supply of 5,2 21 GWh/a (depending on site) Functoinality wind power plants 10
  • Where does the power come from? Die Kraft dahinter! Lifting force 11
  • A plank in the wind creates a load Lifting force 12 direction
  • This load (Fa) = lifting force, Is calculated by Different factors Lifting force 13 direction
  • 1. The wind speed (v) Slow wind = small load Lifting force 14 directiondirection
  • Strong wind = high load But in square ! Double Wind speed means 4 times of load ! Lifting force 15 direction
  • 2. The face (A) Small face = low force Lifting force 16 direction
  • Great face = great load Lifting force 17 direction
  • 3. The air density (r/2) Rare air = small load Lifting force 18 direction
  • Thick air = high force Remark: The air thicknes shifting close to ground (< 1000m) is insignificant! Lifting force 19 direction
  • 4. The lift coefficient (CA) Bad aerodynamic = small force Lifting force 20 direction
  • Good aerodynamic = high force Lifting force 21 direction
  • Lift distribution on a rotor blade V Rotor = 0 km/h V Rotor = 300 km/h
  • The rotor blade leading edges produces: The speed of the rotor blade heads to zero in the center. The lifting power squares with the the wind speed. The reason why the blade tips are responsible for the main part of produced energy. Where is the vast bulk from? 23
  • And what has this to do with airborne wind energy? 24
  • A cut through the rotor blade 25
  • Two tips together are comparable with a kite 26
  • Kites are flying rotor blade leading edges 27
  • The optimal flight patterns is a horizontal position of an 8. How kites fly Energy kites are able to fly in the optimal flight level ! High at weak wind, low if wind is to strong ! A conventional wind turbine is not able to stoop down ! 28
  • The horizontal flight pattern scheme 29
  • With increasing level not only wind speed is increasing but also the intensity
