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

Energy production Energy- consumption
X-Wind power: Kites pulls powerhead = energy production,
powerhead runs = give a lift or hold kite in the air 35 35
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! 41 41

Contribution to grid stability Technology is able to reduce its
installed capacity within 10 sec. negative control reserve
(switching from generation to engine mode) Is perfectly qualified
for the provision of secondary and tertiary control reserve
Therfore, technology can provide a substantial contribution to the
