10. 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 m², a
capacity factor of 10-40%
and an energy supply of
5,2 – 21 GWh/a
(depending on site)

11. Where does the power
come from?
Die Kraft dahinter!

12. A plank in the wind
creates a load
Lifting force

13. This load (Fa)
= lifting force,
Is calculated by
Different factors
Lifting force

direction
14. 1. The wind speed (v)
Slow wind = small load
Lifting force

directiondirection
15. Strong wind = high load
But in square ! Double
Wind speed means
4 times of load !

16. 2. The face (A)
Small face = low force
Lifting force

direction
17. Great face = great load
Lifting force

18. 3. The air density (r/2)
Rare air = small load
Lifting force
18
direction
19. Thick air = high force
Remark: The air thicknes shifting close to ground (< 1000m) is insignificant!

20. 4. The lift coefficient (CA)
Bad aerodynamic = small force
Lifting force

direction
23. 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?

24. And what has this to do with airborne wind energy?
24
28. 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 !

41. Wind energy costs comparable with fossil fuels
• 120 GWh/year = 1 NTS-plant
• Starts at 2.5 m/sec, operates at 300 m
• 120 GWh/year = 60 x 1 MW windmill
• Starts at 5 m/sec, operates at 120 m
• Investment > 70 mil €
For the first time in history wind will produce energy comparable to fossil fuels!
